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.
PD-LD, Inc. offers a broad range of photodiodes and APDs with fiber connection or optical receptacle.
Detectors are available with an FC, ST, or SC connector or as fiber-coupled versions with core diameters from 3 – 200 µm. The fiber end is either open or equipped with an optical connector (PC or APC polishing is possible).
Depending on the integrated photodiode the spectrum ranging from
can be detected very efficiently up to a bandwidth of 3.5 GHz.
Customer-specific photodiodes can be integrated upon request.
Applications for these detectors can be found in fiber optical data transmission (CATV), measurement devices (OTDR), process control, optical sensors, and alignment systems.
