Fiber-Optic Detector, 500-890 nm Battery Biased GaAs Detector, 12.5 GHz, FC/UPC

The 818-BB-45F High Speed Battery Biased Fiber-Optic Detector features a 1 meter long FC connectorized singlemode fiber coupled to a 500 to 890 nm GaAs high speed photodetector with a <30 ps rise time. It includes a built-in bias supply consisting of one standard 3 V lithium cell (3V total bias) and a 50 ohm BNC connector output. The photodetectors have an internal 50 Ω termination. As the responsivity data is applicable to the diode only, the detector output should be determined based on 1/2 the responsivity of that shown on graph. 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. These detectors are suitable for applications where detector rise times 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. It is equivalent to Coherent's Model ET-4000F (P/N 120-10081-0001).
