High Speed Photodetector, 400-900 nm Battery Biased GaAs Detector, 12.5 GHz

The 818-BB-45 High Speed GaAs Detector consists of a free-space 400 to 900 nm battery biased GaAs photodetector with a 0.04 mm active diameter and a <30 ps rise time. It includes a built-in bias supply consisting of one standard 3V lithium cells and a SMA connector output. It is a low-cost solution for ultra-fast measurements up to a 12.5 GHz bandwidth. This detectors are suitable for applications where detector rise time of <30 psec are required for Q-switched and Ultrafast Laser output analysis. 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. 818-BB Series Biased Photodiode Detectors are cost effective diagnostic tools suitable for a variety of high speed applications such as viewing of Q-switched, mode-locked, or rapidly modulated laser signals and picosecond laser alignment.

NOTE-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.
