GaAsP photodiode.

GaAsP photodiode is a photosensor with suppressed sensitivity in the long wavelength range compared to Si photodiodes. It has spectral response close to the human eye sensitivity and is suitable for spectrophotometry, color sensing, etc.

Our photodiodes cover a broad spectral range, from near-infrared and ultraviolet wavelengths to high-energy regions. Available in metal, ceramic.

GaAs photodiodes have peak sensitivity at about 850nm and do not extend more than 25 to 50nm above and below that peak. Photodiodes offer the fastest response time of all silicon-based sensors, but signal levels are in the microamp to tens of microamps range.
