The 818-BB-31 High Speed Photodetector consists of a free-space 1000 to 1600 nm biased InGaAs detector with a 0.10 mm active diameter and a <175 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. 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.
