The 818-BB-36 High Speed InGaAs Detector is built from a free-space extended InGaAs photodiode with a 20 um active diameter and a fast <16 ps rise time. It works well in high-frequency heterodyne applications, time domain, frequency response measurements and monitoring output of ultrafast lasers. It includes a built-in battery-powered 3V bias, an on-off switch and an SMA connector output. The batteries are easily replaceable and by disconnecting the detector from the oscilloscope input, when not in use, you can extend the lifetime of the batteries.
The 818-BB-30, -31, and -35 consist of free-space, small and large area InGaAs detectors, with rise times ranging from 300 ps to 1.5 ns for covering the 1000-1600 nm wavelength range. Each unit includes a built-in bias supply consisting of standard 3 V lithium cells and a 50 ohm BNC connector output. The 818-BB-51 features an extended InGaAs photodetector with a wavelength range of 1475–2100 nm.
An 8-32 threaded hole at the bottom of 818-BB biased photoreceivers allows for optical post mounting.
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.
