PIN photodiodes convert light to current – without a bias voltage having to be applied. Silicon is commonly used as an inexpensive detector material in the Vis range. For higher demands, InGaAs is used; it covers the widest spectral range from the Vis to the NIR. We offer silicon carbide as a “solar-blind” detector specifically for the UV range.
400 nm – 2,100 nm. PD-LD, Inc. offers a broad range of photodiodes and APDs with fiber connection or optical receptacle.
