FAQs

• What is SWIR?

  SWIR is the short form for Short Wave Infrared, which is light invisible to human eyes between the wavelength range from 900nm to 1700nm. Together with Medium Wave Infrared (MWIR) and Long Wave Infrared (LWIR), the three wavelengths constitute the infrared wavelength. SWIR can not be seen with human eyes, but it has excellent sensitivity, as well as the ability to penetrate through fog, smog, cloud, and haze.

• What is SWIR imaging?

  SWIR imaging (Short-wave Infrared imaging) is an advanced technique, which is used to produce images based on radiation in the region of the electromagnetic spectrum invisible to the human eye.

• The Benefit of SWIR?

  InGaAs, short for Indium Gallium Arsenide, is an alloy of Indium Arsenide and Gallium Arsenide, which is a perfect material for short wave infrared imaging sensor with a sensitivity range from 900nm to 1700nm. InGaAs sensor is operable in low light environment under room-temperature without cooling, and it has good responsivity, low noise and low dark current at a reasonable cost.
