ABOUT US

Sensors Unlimited, a part of Collins Aerospace, is the world’s leading manufacturer of indium gallium arsenide (InGaAs)-based imaging products. As renowned experts in shortwave infrared (SWIR) imaging, Sensors Unlimited, Inc. introduced the world to the concept of imaging in the shortwave IR spectrum with simple, compact, and uncooled cameras.

We offer a wide variety of InGaAs-based products, such as high performance, near-infrared (NIR) and SWIR cameras, and 1- and 2-dimensional focal plane arrays for use in military, aerospace, biomedical, commercial and industrial applications. Our in-house indium gallium arsenide III-V foundry features Class 100 clean rooms and an MOCVD epitaxial growth wafer fab, plus a 20,000 square foot detector manufacturing facility.

ADVANTAGES
The advanced InGaAs detector technology allows imaging in the SWIR without the necessity of an external cooling system. Other benefits of our proprietary sensor technology are low power consumption and the ability to image at high frame rates, a remarkable advantage over current uncooled microbolometer technology. Our NIR cameras deliver what thermal imagers cannot – clear, lifelike detection in daylight or lowlight. Small and compact, they operate at room temperature with no moving parts and can image through glass and plastic using off-the-shelf glass optics. Because our InGaAs cameras have non-uniformity corrections (NUCs) that last for the lifetime of the cameras, they do not need NUCs in the field, making operation simpler.

APPLICATIONS
InGaAs arrays and imagers are ideal for a wide variety of military, industrial, biomedical, telecommunications, scientific and commercial applications. These include:

  • Laser tracking for weapons and communication systems
  • Covert and fixed site surveillance
  • Free space communications
  • Ground and air UV payloads
  • Gimbal sensor assemblies
  • Night vision
  • Near-infrared spectroscopy
  • High speed imaging and tracking
  • Target recognition
  • Driver vision enhancement
  • Food processing and inspection
  • Laser beam profiling
  • Imaging hot processes, e.g. glassmaking and metal smelting
  • Security and surveillance
  • Linescan inspection
  • Microscopy
  • Art conservation
  • Astronomy

Sensors Unlimited’s Non-ITAR, Low-Cost Micro-SWIR 640CSX Series of video cameras are ideal for commercial and military applications involving low-light-level imaging and imaging through atmospheric obscurants, such as fog, dust, and smoke.  Other applications include covert surveillance, multi-laser spotting and tracking, and tasks with low SWaP (size, weight, and power) and high-sensitivity requirements. Its compact size also makes it ideal for integration into UAS, handheld, and soldier-mounted systems.

Sensors Unlimited offers the Mini-SWIR™ JSX Snapshot Camera, the 1280JSX, designed to provide real-time daylight to low light imaging in SWIR wavelengths. This version has a 60 FPS full frame rate and can be used in Driver Vision Enhancement (DVE) systems, in low-light level imaging applications, for covert surveillance in day or nighttime conditions, imaging through atmospheric obscurants, and for multi-laser spotting and tracking in military operations.

Sensors Unlimited – A part of Collins Aerospace introduces their new LDM series of compact, InGaAs SWIR line scan camera for machine vision, sorting, & solar inspection. The 1024LDM line-scan camera features high resolution, 1024-pixel imaging in the shortwave infrared (SWIR). Its square pixels are ideal for inspection of polished silicon blocks, ingots, or wafers, hot glass bottles, and for use on continuous-process lines that apply transparent coatings which can be ‘seen’ in the SWIR spectral region.

The 2048R SWIR InGaAs linescan camera’s high resolution, stability, and reliability make it ideal for Optical Coherence Tomography (OCT) applications studying blood flow or large tissue volumes at 1.04, 1.32, and 1.55 µm, high-resolution spectroscopy of transient spectra from .940 to 1680 nm, and SWIR machine vision of ultrafast moving objects.

Sensors Unlimited – A part of Collins Aerospace introduces the GL2048L camera providing high-resolution line capture using 2048 pixels on 10-micron pitch for both machine vision and for Optical Coherence Tomography (OCT) with high QE in the 1 to 1.6 micron wavelength range.  The camera covers the line rate range from 100 to >76,000 lines per second via 12-bit base Camera Link® digital interfaces providing flexibility. It can also be externally triggered over the interface to set both the line rate and exposure time via the frame grabber CC1 signal.

The extended wavelength LC-series linear InGaAs photodiode arrays from Sensors Unlimited – A part of Collins Aerospace are designed for broad wavelength range, multi-channel spectrometer designs. The proprietary readout integrated circuit design contains functions that reduce dark current for applications that demand the highest performance. The LC package provides a “no moving part” solution for vibration resistant, highly calibrated instruments that require long term stability. Ideal applications include industrial process control and inspection in agricultural sorting, biomedical analysis and thermal imaging.

The LDB/LSB Series from Sensors Unlimited generally is used for monitoring optical performance of S, C, & L band channels in DWDM networks, and for agricultural sorting, biomedical analysis, thermal imaging, and industrial process control.

For 1.31 μm SD-OCT, diode array-based OCT systems offer superior phase stability for doppler or polarization-sensitive OCT.

The GEM III is a multifunctional night vision device with a wide variety of configurations for an array of cameras, camcorders, lenses, and scopes for covert surveillance operations. This device is capable of true night vision in the world of still and full-motion digital image capture, and is able to change between configurations in a short amount of time without the use of tools.

INDUSTRIES & APPLICATIONS

As the US continues to increase its security at border crossings, airports and other points of entry, biometrics will play an important role. Fingerprints and other direct contact means will become final identifiers of persons.

Manufacturers of glass hollowware have long sought a way to pick out defective product at the hot end of their process, while the pieces are still above 200ºC. At that glass inspection stage, rejects are identified, then shunted aside and reprocessed efficiently, greatly reducing scrap. 

 

Responding to the Global War on Terrorism (GWOT) has become the focus of U.S. Defense policy, and with that, the need for greater intelligence collection has moved upward in priority. Whereas past reconnaissance needs were more strategic in nature, today's needs are highly tactical, demanding a high level of persistence and the ability, in many cases, to identify individual humans in the field of interest. In recent years, the exceptional capabilities of short wave infrared (SWIR) technology have made SWIR the "Next Generation" of imaging technology for ground, airborne and space technology.

Indium Gallium Arsenide (InGaAs) is the most common material used in infrared spectroscopy for studying light in the wavelength range of 0.9 to 1.7 microns. Innovative research and production of InGaAs material with high quantum efficiency (QE) and low dark current has made Sensors Unlimited the world leading supplier of linear photodiode arrays for IR spectroscopy camera systems.

Contactless machine-vision inspection using photoluminescence (PL) imaging with shortwave infrared (SWIR) cameras can help solar cell producers improve both efficiency and quality of their photovoltaic products. Inspection of silicon bulk ingots, sliced wafers, processed layers, and complete photovoltaic cells is possible with SWIR imaging.

Multi-spectral electroluminescence and SWIR imaging can be used to separately inspect multi-junction uniformity and relative output.

By using the 1.05 µm central wavelength, instrumentation companies are now developing systems to image deeper through the retina into the blood vessel layer (called the choroid) to diagnose eye diseases and monitor treatment.

Developed by MPB Communications Inc. the GHGSat’s microSat, nicknamed "Claire," celebrates its second year in space this June. Flying a Sensors Unlimited 640HSX InGaAs SWIR Camera, this micro satellite circles the Earth every 90 minutes collecting infrared images. 

Short wave infrared (SWIR) cameras can extend vision into wavebands normally invisible to the eye and other types of thermal imaging. These near and shortwave IR images reveal details in clear, lifelike form.
