The 818-BB-45F High Speed Battery Biased Fiber-Optic Detector features a 1 meter long FC connectorized singlemode fiber coupled to a 400 to 900 nm GaAs high speed photodetector with a <30 ps rise time. It includes a built-in bias supply consisting of two standard 3 V lithium cells (6V total bias) and a 50 ohm BNC connector output. This cost effective diagnostic tool is 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. 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.
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.
