Specifications

Features

Silicon Optical Receiver

The 818-BB-21A features a 0.4 mm diameter silicon photodetector with a wavelength range of 300 to 1100 nm.  This 24 V biased free space receiver has an acceptance angle of 10°. The Amplified PIN Photodetector utilizes the photovoltaic effect to convert optical power into an electrical current.

InGaAs Optical Receiver

The 818-BB-30A features a 0.1 mm diameter InGaAs photodetector with a wavelength range of 1000 to 1600 nm.  This 24 V biased free space receiver has an acceptance angle of 20°. The Amplified PIN Photodetector utilizes the photovoltaic effect to convert optical power into an electrical current.

Measure Pulsewidth or Frequency Response

These high speed detectors make a great free space front end for an scope or spectrum analyzer. When terminated into 50Ω into an oscilloscope, the pulsewidth of a laser can be measured. When terminated into a spectrum analyzer, the frequency response of a laser can be measured.

Optical Post Mounting

An 8-32 threaded hole at the bottom of 818-BB biased photoreceivers allows for optical post mounting.

Handle With ESD Care

These detectors are very susceptible to damage by electrostatic discharge (ESD). Please use ESD protective measures, like the FK-STRAP , when unpacking and handling these devices.
