Photo detector

Photosensors or photodetectors are sensors of light or other electromagnetic energy. The absorbed photons make electron–hole pairs in the depletion region. Photo detectors are used primarily as an optical receiver to convert light into electricity.

Excellent linearity of the output current with respect to incident light. All photodetectors contain their own BNC or SMA output connector.

Connecting the photodetector to an oscilloscope and terminating into .

The photodetector is as essential an element of any fiber optic system as the optical fiber or the light source. Semiconductor photodiodes are the most commonly used detectors in optical fiber systems since they . Infrared light emitting and receiving devices supporting photosensor and IrDA.

We offer high speed photo detectors with special photodiodes for converting optical signals to electrical fast signals for optical measurement. High speed fiber-optic detectors use special photodiodes with high speed electronic circuits to convert fast pulses in optical fibers to electrical signals for measurement. With our comprehensive testing and direct NIST traceability our low power photodiode sensors provide measurement you can trust when measuring optical power from free-space and . But unlike PMTs which use multiple dynodes as electron . Discover our photo detectors and other products.

Depending on the application, a photodetector has to fulfill various requirements: It must be sensitive in some given spectral region (range of optical wavelengths). In some cases, the responsivity should be constant or at least well defined within some wavelength range. It can also be important to have zero . High-Speed Detectors and Receivers. Though the active device structure of the RCE detectors remains close to other conventional photodetectors, the effect of . Noise Equivalent Power (NEP) is determined via open circuit output. More benign environments where any potential fire will be slow burning can be protected using the optical detector.

Photoelectrons emitted from the photocathode are directly bombarded onto the semiconductor to multiply the photoelectrons. This method allows efficient electron multiplication with less . InGaAs (Indium Gallium Arsenide) Photo Detectors.
