What is SWIR imaging?

(SWIR) Short-wave Infrared imaging is an advanced technique, used for producing images based on radiation within the electromagnetic spectrum. Infrared radiation is located between visible light and microwaves between 0.75 µm – 1mm wavelength. Infrared is split between 5 regions: Near-Infrared (NIR), Short-Wave Infrared (SWIR), Mid-Wave Infrared (MWIR), Long-Wave Infrared (LWIR), and Far Infrared (FIR). SWIR cameras can see even at night and under hard visible conditions lie clouds, smoke, or even dust. Another major benefit of SWIR imaging that is the ability to image through glass, great for inspection of products with no destruction. 

What is a InGaAs sensors?

InGaAs is an arcanum for the element composition of the material it makes (Indium, Gallium, Arsenide).  NIT has developed and invested into a manufacturing line of InGaAs sensors using a unique and proprietary technology. InGaAs annoy absorbs IR light invisible to silicon and converts incident light into electrons digitized by the ROIC and the camera electronics. Adding this array to a ROIC, read-out integrated circuits, can be a challenging task in design and engineering.  One of the critical steps is the 3D stacking of the photodiode array to the read-out circuit, for which NIT has developed a very innovative flip chip process ensuring the CMOS read out circuit at a sub-micron precision high yield and low cost of production.

What applications is SWIR imaging used in?

SWIR imagers are used in a large number of applications including semiconductor inspection, laser alignment and beam profiling, hot glass inspection, security and surveillance, machine vision imaging, agricultural sensing, microscopy and life science imaging.
