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.

Sensors Unlimited offers the compact SPS (SWIR Pocket Scope) field-ready viewer designed to provide high resolution video within day time and nighttime operations. It delivers distinct advantages over other viewer technologies, including visible (CMOS), thermal, and night vision systems. 

Sensors Unlimited offers the SPS+MMT, SWIR Pocket Scope + Multi Mode Tracker, designed to provide high resolution video with laser tracking and decoding of up to 3 independent sources. Available capabilities include simultaneous tracking and decoding, out of band SWIR imaging (0.7 to 1.7 µm), enhanced battle damage assessment, and reduced fratricide and collateral damage.

Sensors Unlimited’s 1024-LDH2 is a high-speed 1024-pixel, line scan, InGaAs camera that increases the A-line rate to 91,911 lines per second to enable spectral domain OCT to capture detailed 3-D volumes of the retina, nerve head, and choroid layer in the blink of an eye. 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.

As the U.S. continues to increase its security at border crossings, airports, and other points of entry, biometrics will play an important role. SWIR cameras can help identify disguises as the border and therefore supplement security efforts.

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.

Flying a Sensors Unlimited 640HSX InGaAs SWIR camera, the GHGSat’s microSat circles the Earth every 90 minutes collecting infrared images. Data from the microSat will enable industries to monitor and quantify their own carbon dioxide and methane emissions to better manage and reduce their impact on air quality.

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.
