The SD138-11-31-211 features two silicon PIN photodiodes in a vertically-integrated, hermetic TO-5 package.
API's amplifiers are highly resistant to external noise and suitable for compact circuit design.
API's Multi-element silicon photodiodes provide a cost effective alternative in applications requiring several photodiodes.
API's photodiodes have no internal gain, but can operate with a significantly greater dynamic range than other types of photon detectors.
API's low cost cadmium sulfoselenide sensors for visible light measurement designed to sense light from 400-700 nm.
Avalanche photodiodes and modules offers high internal gain and improved S/N ratios.
