Germanium Photodetectors leverage the semiconductor properties of germanium to detect optical signals across the near-infrared and short-wave infrared spectrum, typically from about 800 nm to 1800 nm. Germanium’s smaller bandgap than silicon enables efficient absorption at wavelengths important for fiber-optic communications, gas sensing, and industrial inspection. GPD produces high-quality germanium photodetectors optimized for low noise, fast response, and reliability, making them well-suited for both commercial telecom infrastructure and demanding defense and scientific sensing applications.
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.
