Silicium photodiodes have a detection range from 200 – 1100 nm. Special produced silicium photodiodes can even detect the UV and soft X-ray range from about 0.07 nm up to 1100 nm.
SphereOptics delivers with OSI Optoelectronics different types and designs of Si-Photodiodes.
For example avalanche photodiodes for Lidar application, photodiodes arrays and PSDs for position measurement, high speed photodiodes, Nd:YAG X-ray and UV-photodiodes, color sensors, solderable photodiodes and molded optoelectronical components for industrial applications.
GaAS photodiodes have a detection range from 400 – 850nm and they are used mostly for high speed optical data communication.
