The 818-BB-21 High Speed Silicon Optical Detector consists of a free-space 300 to 1100 nm Battery Biased Silicon detector with a 0.40 mm active diameter and a <300 ps rise time. It includes a built-in bias supply consisting of three standard 3 V lithium cells (9 V 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.
The 818-BB-21 and -40 consist of free-space, small and large area Silicon detectors, with rise times ranging from 300 ps to 1.5 ns. Each unit, other than the 818-BB-40, includes a built-in bias supply consisting of standard 3 V lithium cells and a 50 ohm BNC connector output. The 818-BB-40 comes with an external 24 VDC power supply.
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.
