High Speed Photodetector, 1000-1650 nm Battery Biased InGaAs Detector, 15 GHz

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.

The 818-BB-35 and 818-BB-45 photodiode detector modules offer a low-cost solution for ultra-fast measurements offering a 12.5 GHz bandwidth. These detectors are suitable for applications where detector rise time of <25 ps (<30 ps for 818-BB-45) are required for Q-switched and Ultrafast Laser output analysis. These detectors also utilize 3 V lithium cells (supplied).
