Standard InGaAs has a long wavelength cutoff of 1.68 µm. Meaning, it is sensitive to the wavelengths of light that suffer the least signal dispersion and transmit furthest down a glass fiber (1.3 µm and 1.55 µm), therefore detecting "eye-safe" lasers (wavelengths longer than 1.4 µm).

InGaAs photodiodes for near-infrared light detection. Features include high speed, high sensitivity, low noise, and spectral responses ranging from 0.5 μm to 2.6 μm.

InGaAs (Indium Gallium Arsenide) is a semiconductor material known for its sensitivity to infrared (IR) light, making it an essential component in various optical applications.

PIRT has a unique InGaAs detector structure, which allows for low noise and the ability to image from 0.4 to 1.7 µm with high Quantum Efficiency. Quantum Efficiency is how effective the material converts photons detected to electrons that can be measured.
