Marktech MTMD34679PD6T38 – SWIR multi-chip emitter-detector with multiple wavelength LEDs

April 23, 2024 – Latham, NY, USA –  Marktech Optoelectronics, Inc. (www.marktechopto.com)(Marktech), a privately-held leading designer and manufacturer of standard and custom optoelectronics, including UV, visible, near-infrared (NIR), and short-wavelength infrared (SWIR) emitters, detectors, InP epi wafers, and other compound semiconductors, today reveals their new multi-chip packages combining InGaAs photodiodes and multiple SWIR LEDs in the same package. These products join a growing line of multi-chip products consisting of multi-wavelength LEDs (UV through MWIR) with or without InGaAs, silicon, or InGaAs+silicon detectors.

Our range of multi-chip products includes:

  • Multiple LEDs in a single package (235nm to 4300nm wavelength combinations)
  • Multiple detectors in a single package (multiple silicon, InGaAs, and SiC photodiodes)
  • Multiple LEDs + single or various detectors in a single package
  • Packaging options include SMD, TO-can, and our award-winning ATLAS hermetic SMD

ATLAS hermetic SMD packages are ideal for LED, detector, & multichip applications.

 

Co-Packaged InGaAs Photodiodes with Multiple LED Emitters

Our newest multi-SWIR LED emitters + detector components include part numbers MTMD1479PD6T38 and MTMD34679PD6T38. MTMD1479PD6T38 includes 1460nm, 1720nm, and 1900nm SWIR LED chips combined with a 2.6µm InGaAs detector providing 800nm to 2600nm responsivity. MTMD34679PD6T38 has the same 2.6µm InGaAs detector co-packaged with 1300nm, 1460nm, 1650nm, 1720nm, and 1900nm SWIR LEDs. To the best of our knowledge, our 2.6µm InGaAs detector has the highest responsivity on the market based on our internal tests and customer evaluations comparing our InGaAs detectors with our competitor’s products.

Marktech’s UV, visible, NIR, and SWIR emitters combined with our IR detectors (InGaAs photodiodes) are the perfect solution for many analytical, medical, aerospace, and industrial sensing applications. An additional silicon detector can be added to the package when UV LED light needs to be monitored or detected. The co-packaged emitters are individually addressable. Multiple chip products are available in TO can and SMD packages.

Multiple Wavelength Multi-chip Products

For applications such as transmission spectroscopy requiring a multiple-wavelength source separate from the detector, Marktech also produces multi-wavelength -devices consisting of multiple LED chips in a single package.

Our newer LED light sources, Multiple wavelength LED emitters, have several advantages over singularly packaged LEDs and older, conventional light sources. Co-packaging multiple LED emitters can:

  • Ability to rapidly vary light power output and wavelength
  • Reduce Circuitry & Simpler Design
  • Reduce Part Count
  • More compact design – ideal for wearable applications
  • High-speed wavelength selection
  • No or minimal heat dissipation – reduce heat compared to halogen, xenon, mercury vapor, or thermal IR emitters
  • Reduce power compared to halogen, xenon, mercury vapor, or thermal IR emitters
  • Increase life compared to halogen, xenon, mercury vapor, or thermal IR emitters
  • Fast response (on/off or pulsing) – no warm-up delay of halogen, xenon, mercury vapor, or thermal IR emitters
  • Elimination of moving parts – e.g., motorized slit in dispersive spectrometers
  • High emission stability – no or minimal wavelength drift over the lifetime

Our multiple LED and multi-detector products are available in several variations:

  1. Multiple emitters combined with InGaAs photodiodes for Vis-NIR-SWIR detection
  2. Multiple UVC LEDs (235nm, 255nm) with SiC photodiodes for deep UVC emission and detection
  3. Multiple emitters joined with silicon photodiodes for UVB-Vis-NIR emission and detection
  4. Multiple emitters sharing the same package with both InGaAs and silicon photodiodes for UVB-Vis-NIR-SWIR detection
  5. Multiple InGaAs, silicon, and InGaAs-silicon detector combinations with different emission filters on each photodiode
  6. Multiple InGaAs, silicon, and InGaAs-silicon detector combinations with integral transimpedance amplifiers (TIAs)
  7. Multiple InGaAs, silicon, and InGaAs-silicon detector combinations with thermionic coolers
  8. Multiple LED emitters of multiple wavelengths
  9. Multiple LED emitters of the same wavelength for increased power

Multiple emitters in one package ( up to 7 in our standard thru-hole or SMT package) along with detectors in a separate package (4, 5, & 6) can be helpful in colorimeter and color photometer applications using cuvettes where the excitation light is transmitted through the sample – or, where the excitation wavelength(s) needs to separate from the photodiode detector(s).

The specific combinations of emitters and detectors can be tailored or “mixed and matched” to your application’s specific light source and detection requirements.

In applications requiring higher power, multiple LED die of the same wavelength are placed in the same package. For example, Marktech’s MTMD4270T38 product contains two 428nm LEDs and two 700nm LEDs. Our MTMS1300N24 SWIR LED emitter contains three 1300nm chips in a narrow domed lens TO-can package. Our  MTMD7885T38 multiple wavelength emitter has three 770nm die in a PLCC package. Our MTMS7700T38 (770nm), MTMS8800T38 (880nm), and MTMS9400T38 (950nm) products utilize six LED emitter chips in the TO-can package.

Examples of Marktech’s multiple wavelength, multi-chip LED products

InGaAs detectors and InGaAs photodiodes with multiple LEDs are beneficial in a variety of applications, such as:

  • Biomedical instrumentation
  • Black ice detection
  • Broadband, hyperspectral, and multispectral light sources
  • Colorimetry
  • Contamination or foreign material detection
  • Counterfeit currency detection
  • Curing / Crosslinking
  • Endoscopic lighting and tissue oximetry
  • Fluorometry
  • Fluorescence microscopy
  • Functional near-infrared spectroscopy (fNIRS)
  • FURA / calcium imaging
  • Glucose monitoring
  • Industrial machine vision
  • Iris matching or recognition for biometrics
  • NIR spectrometry
  • Optical communications
  • Optogenetics
  • Oximetry / Co-oximetry
  • Photodynamic therapy
  • Photometry
  • Solar simulation
  • Sorting equipment
  • Spectroscopy
  • SWIR Detection
  • SWIR Imaging

In some applications, the integral detector acts as a monitor to indicate the LEDs are emitting light. In other cases, the InGaAs can detect reflected or fluorescence emission from a sample illuminated by the LEDs. For example, oximeters, NDIR, and fNIR devices can emit and detect the reflected or partially transmitted light to determine oxygen levels in the tissue. For applications that require light transmitted through a sample and then detected, Marktech can package the LEDs and InGaAs detectors separately.

In dispersive spectroscopic analysis, a monochromator generates a wide range of wavelengths. Monochromators employ a prism or diffraction grating combined with a motorized slit to select a specific excitation wavelength. Typically, we look at the peaks of an unknown chemical or material analyte and compare them to libraries of identified reference spectra.

In specific applications with unknown amounts of known analytes in a closed system, only a few specific wavelengths are required to distinguish between and quantify particular chemical constituents. Examples of applications where a selection of specific wavelengths is helpful in chemical analyte quantification include:

  • Spectroscopically analyzing the amount of reactant in a chemical production process
  • Colorimetric analysis of process, drinking, or wastewater contaminants
  • Oximetry, optical glucose monitoring, ischemia detection, and other medical diagnostics
  • Fluorometry for fluorescence identification of minerals or biological materials
  • Fluorescence microscopy for life science imaging (cells, proteins, biological materials)
  • Non-dispersive infrared (NDIR) spectroscopy-based gas analyzers or gas sensors

In one of these “closed systems” with multiple analytes, sometimes the more efficient option is not to choose wavelengths corresponding to the peaks of the analytes but rather a few wavelengths producing the most significant differences between the analyte’s absorption, reflectance, transmission, or fluorescence. With this methodology, fewer LED emitters can often provide better analytical results. In addition, the ratio transmission results from two or more wavelengths can account for slight interference in turbid or dirty samples.

Multiple LEDs in Spectrometry, Fluorimetry & Fluorescent Microscopy

Eliminating the monochromator combined with LED emitters’ higher natural monochromatic nature can produce a higher power excitation light source than a dispersion spectrometer with broadband xenon, halogen, and mercury sources. In dispersion spectrometers, conventional light sources are broken into 128 or 256 wavelengths, with each wavelength having only a fraction of the energy of the source. Higher-power LEDs at specific peak wavelengths can improve the signal-to-noise ratio.

When comparing or discerning two analytes, specific wavelengths provide no additional information when the absorption levels of the two species are equivalent. Therefore, eliminating these wavelengths and using a few critical discerning wavelengths can speed up the overall detection process.

In addition, since a handful of the target excitation wavelengths are picked, each wavelength source can be optimized for high power output and increased wavelength monochromaticity. For instance, additional LEDs with the same wavelength can be packaged in the same TO can, PLCC, or SMD package to provide higher power for a particular wavelength. In addition, Marktech can sort or bin LED emitters to produce tuned LEDs with minimal peak wavelength variation of ±1nm. In higher-volume applications, wavelength variation and power output can be adjusted at the wafer level or in the light-emitting diode fabrication process. Likewise, InGaAs and silicon detectors can be customized during semiconductor fabrication to specific sensitivity ranges – when production volumes warrant the development.

Fluorometers (fluorescence spectrometers) and microscopes utilize a specific excitation wavelength capable of exciting a fluorescent dye or fluorophore in a sample, emitting at a peak emission wavelength. Cells, tissues, and other biological samples are often examined with fluorescence. LEDs eliminate several problems in fluorescence studies compared to older light sources, such as overexposure to light, thermal damage and phototoxicity of the biological sample, and photobleaching of fluorescent dyes or proteins. The peak wavelength of the LEDs can be selected to match the excitation wavelengths of the fluorophores closely. Combined with the higher intensity or power output at the peak wavelength, the result is improved signal-to-noise in fluorometry and fluorescence microscopy applications. Our multi-wavelength LED packages enable the selection of a different excitation wavelength for different fluorophores, fluorescent dyes, or color-indicating reagents. For instance, our MTMD2336T38 multi-wavelength light source can selectively emit 275nm, 310nm, 360nm, and 380nm wavelengths, and our MTMD3334T38 multi-wavelength light source can selectively emit 310nm, 360nm, 380nm, and 430nm wavelengths.

NIR and incredibly SWIR wavelength light can penetrate deeper into human tissue than visible light due to the reduced photon scattering at these wavelengths. SWIR’s high penetration depth enables imaging and spectral information collection deep into tissues. Some of these NIR/SWIR infrared imaging systems have mapped blood flow in live animals and imaged tissue 5mm into mouse brains. In addition, infrared spectroscopy can provide information on deep tissue chemical composition, such as oxygenation and deoxygenation. In the article, “Shortwave infrared fluorescence imaging with the clinically approved near-infrared dye indocyanine green,” the researchers stated that “imaging in the shortwave IR (SWIR; 1,000–2,000 nm) promises higher contrast, sensitivity, and penetration depths compared with conventional visible and near-IR (NIR) fluorescence imaging.” The researchers used NIR and SWIR light sources with an InGaAs detector. Marktech has many singular and multi-wavelength LED emitters in the NIR and SWIR wavelength ranges. For example, the Marktech MTMD142345PDT38 multiple SWIR wavelength emitter-detector contains 1040nm, 1200nm, 1300nm, 1460nm, and 1550nm peak wavelength LEDs combined with our InGaAs photodiode for SWIR detection in the 600nm – 1750nm range. These SWIR emitter-detectors can be helpful in tissue oxygenation and utilization studies using NIRS methods.

In summary, spectrometry, fluorescence microscopy, and other optical analytical methods performed with a specific set of multiple LED light sources and the appropriate photodiode detector can have improved signal-to-noise ratio and detection speed.

Maximize Your Total Cost Benefit with Tailored Photodiodes and LEDs for OEM Designs

Maximize Your Total Cost Benefit with Tailored Photodiodes and LEDs for OEM Designs

Photodiodes and LEDs are widely used in a range of applications, including optical sensors, communication systems, medical diagnostic devices, analytical instruments, and application specific lighting. They are often used together to maximize the total cost benefit, with photodiodes serving as detectors and LEDs as emitters. By tailoring these components to OEM design needs, engineers can optimize performance while minimizing costs.

Photodiodes are semiconductor devices that convert light into an electrical current. They are commonly used in applications such as light detection and communication systems, where they can be used to detect changes in light intensity or to transmit data via optical signals. Photodiodes can be designed with different materials and structures, such as silicon, SiC, or InGaAs, to optimize their sensitivity and response time for specific applications.

LEDs, on the other hand, are semiconductor devices that emit light when a voltage is applied to them. They are commonly used as light sources in a range of applications, including displays, lighting, and communication systems. LEDs can also be designed with different materials and structures, such as GaN or InGaN, to optimize their emission wavelength and brightness for specific applications.

By combining photodiodes and LEDs together in the same package, engineers can create efficient and cost-effective systems. For example, in a communication system, an LED can be used to transmit data via optical signals, while a photodiode can be used to receive the signals and convert them back into electrical signals. By selecting the appropriate photodiode and LED components for the system, engineers can optimize the performance and cost of the system.

What is total cost benefit?

“Total cost benefit” refers to a comprehensive evaluation of both the financial and non-financial gains that can be derived from an investment, action, or decision, in relation to the total costs involved, including financial expenditures and potential risks. This approach does not just look at the monetary aspect but also considers other benefits such as improved safety, convenience, or time savings, while accounting for all associated costs including potential downstream or auxiliary costs.
To obtain a true sense of the total cost benefit, one needs to examine all potential gains and savings, direct and indirect, tangible and intangible, that may result from the decision, and then compare it against a fully loaded cost profile that encompasses every possible cost, direct and indirect, associated with that decision.
A total cost benefit analysis aims to provide a more rounded view of the value proposition of a decision by exploring it from multiple dimensions, and it is a critical tool in both business and policy making, aiding stakeholders in making informed decisions grounded on a holistic understanding of the potential outcomes. It offers a macro perspective, enabling a thorough evaluation and thereby facilitating choices that are aligned with long-term objectives and holistic wellbeing.

Maximizing Total Cost Benefit with Customization

To maximize the total cost benefit of photodiodes and LEDs, engineers should carefully consider the specific needs of their OEM designs. This includes selecting components that are optimized for the specific application, as well as components that are cost-effective and reliable. It also involves selecting components that are easy to integrate into the overall system design, with minimal additional components required.

For example, in a sensing system, the photodiode and LED components should be selected based on the desired sensitivity and wavelength range of the system. The components should also be selected based on their reliability and cost, with consideration given to the overall cost of the system. Additionally, the components should be designed with ease of integration in mind, to reduce the overall system complexity and cost. Standard or lower cost optoelectronic components often do not minimize the total system cost of a design or the “total cost of ownership”. For example, a design engineer may have planned on buying two separate photodiodes to meet the detection wavelength range requirements of the project. Marktech’s custom solution combined two photodiodes in the same package resulting in a lower total cost and less complicated design compared to purchasing two separate detectors.

In some cases, a detector has more gain than is required for a project. For these optoelectrical design projects, Marktech has custom developed lower active area detectors, which are less costly than a standard photodiodes with larger active areas.

Bacteria or microbes can have sensitivity to destruction at certain wavelengths. For instance, cryptosporidium is sensitive to or most effectively killed by 265nm light. In some sanitization cryptosporidium applications, mercury vapor lamps with a wide spectrum are used. Power is wasted because some of the wavelengths emitted are ineffective at destroying the bacteria Marktech can provide 265nm LEDs specifically targeting cryptosporidium eliminating providing a design with more energy efficiency and longer battery life. Likewise, Marktech can provide 235nm and 255nm deep UVC wavelengths for the detection of creatine, uric acid, proteins, nitrates in water or blood samples.

In addition, off-the-shelf parts frequently cannot provide the optimized performance of a bespoke detector or LED developed specifically for a new electro-optical product design. Even if the overall cost of the system is slightly higher using a custom part than a standard component, the performance per cost is higher or the total cost benefit is lower.

An intangible benefit is the competitive advantage provide provided by unique, custom LEDs or photodiodes. Bespoke optoelectronic parts can provide unique optoelectrical characteristic unlike any catalog type components. A design with a standard component can be more easily reversed engineered and then duplicated. Custom LEDs or custom detectors cannot be duplicated as easily or at all in some cases.

Tailoring LEDs and photodiodes to the specific design requirement can eliminate the need for additional component such as optical filters, amplifiers, lenses, etc. – resulting in lower system cost, higher product performance, or higher total cost benefit.

Marktech Optoelectronics Custom Reticle Capabilities
Custom Reticle Capabilities

LATHAM, NEW YORK… Marktech Optoelectronics, a Latham, New York-based manufacturer of standard and custom optoelectronics, has announced their new custom reticle capabilities. This display technology is used in applications, which include rifle scopes, binoculars, cameras, and range finders. All of Marktech’s reticles include precise illumination for low-light environments and are highly customizable based on customer specifications.

Reticle: A series of fine lines or fibers in the eyepiece of a sighting device used as a measuring scale or an aid in locating objects.

The company has also introduced one of the first 10-micron red dot chips available on the market today. “For shorter distances, a standard 50- to 80-micron red dot is probably fine,” explains Vincent Forte, Marktech’s chief technology officer, “but for longer distances, a 10-micron red dot is preferred; the smaller the dot, the more accurate the device.”

Marktech can design and manufacture a red dot and/or reticle in nearly any shape, size, or configuration, and this unique customization capability gives them an advantage in the industry. “We have the ability to create a reticle and/or red dot in conjunction with a 7-segment numeric or alphanumeric display and/or a 15 to 20-micron crosshair segment,” notes Forte. “We can assemble the die into any type of standard or custom package or chip-on-board [COB] assembly. We can even custom-design a reticle to have the segment and dot independently driven, which is quite unique in the industry.”

Devices that typically use red dots and reticles include telescopes, telescopic rifle sights, microscopes, cameras, binoculars, and other types of instrumentation. Range finders typically use a red dot and reticle in conjunction with an Avalanche photodiode (APD) as the detector, also available from Marktech. The industries most often using reticles and red dots are military, technology, recreation, or anywhere that needs a microscopic illumination source.
