What is InGaAs?

InGaAs, i.e. indium gallium arsenide, is an alloy of gallium arsenide and indium arsenide. InGaAs sensors have a high sensitivity in the infrared region, ranging from 950 nm to 1700 nm, allowing users to detect photons invisible to the human eye.

For active imaging, laser measurements & laser alignemnt (viewer), high temperature thermography, Coastal surveillance, bio medical imaging, waste sorting, 

NIT Short Wave Infrared (SWIR) products are based on a proprietary Wide Dynamic Range ROIC technologies and offer a Dynamic Range (DR) of more than 140dB in a single image without any external control.

The internal Fixed Pattern Noise correction gives a high uniformity picture in all light conditions with no need of Look-up table.

The NIT WDR InGaAs sensors use InGaAs photodiodes array operating from 900nm up to 1700nm with a high QE and coupled to a patented Read Out Circuit (ROIC).

The WiDy camera is the ideal candidate for gated imaging/active imaging thanks to an exposure time as low as 200ns with adjustable trigger delay.


WiDy SWIR is a low-cost InGaAs featuring NIT patented HDR technology (120dB)TEClessvarious output options, delivered with proprietary software and SDK: USB3.0 (WiDyVISION), CameraLink (WiDyCAM), Analog  control using RS232 port (WiDyCirene) and GigE versions.

The WiDy SWIR camera family is perfectly suitable for applications and environments where the light flux could be hard to handle. Delivering a dynamic of 120dB, outdoor applications such as airborne will be a perfect playground for our family member. With an attractive price, the WiDy SWIR offers a sufficient VGA resolution and an image quality valuable for some industrial inspections.

WiDy SWIR HDR InGaAs Camera has a broad range of applications:

Military and Defense : Imaging at long ranges and through obscurants such as fog, smoke, mist, haze, rain.Border security. Rocket missile tracking. WiDy SWIR is a great tool for security and surveillance.

WiDy SWIR enables semiconductor inspection. 

Semiconductor inspection

Photovoltaics (Electroluminescence for PV cells)


Welding: Eliminates the need for neutral density filter. SWIR cameras can see through the plasma or near laser spot, visualize weld pool and measure temperature but the camera needs to be calibrated.

Laser: You can align Telecom components without any saturation on laser. Optimize laser beam profiling. Control Laser micromachining processes.

High Intensity Light Scenes: SWIR cameras can penetrate through glass, smoke and haze(Click here to see video), without saturation on laser or under sun.


WiDy is the perfect Low-cost ingaas camera for laser beam alignment, laser beam tracking. 

The WiDy SWIR 640V-S offers 640 x 512 pixels with 15 µm pixel pitch.

SWIR InGaAs cameras and sensors are designed to provide top performance over a very wide range of light levels, frame rates, and triggering requirements. This insures the SWIR camera delivers top performance as your scene conditions dramatically change. No more compromises or workarounds. For imaging applications between 900-1700 nm, our SWIR cameras with the patented WiDy (Wide Dynamic Range) sensors have 120 db dynamic range. Low-cost ingaas camera by NIT.
