Infrared Detection refers to the sensing of electromagnetic radiation in the infrared portion of the spectrum, spanning wavelengths from roughly 700 nm to beyond 14 micrometers. This capability is fundamental to applications including thermal imaging, remote sensing, gas analysis, medical diagnostics, and defense systems. GPD develops and manufactures photodetectors covering key infrared bands using materials such as InGaAs, germanium, and HgCdTe, providing customers with high-sensitivity, low-noise solutions tailored to the specific wavelength and performance demands of their systems.
Choosing a photodetector isn’t just a spec-matching exercise. The wrong choice drives redesign cycles, calibration overhead, and supplier risk that never appear on a datasheet. Here’s how to evaluate detectors the way your product’s lifecycle actually demands.
