The 818-BB-40 High Speed Silicon Detector consists of a free-space 350 to 1100 nm externally biased Silicon photodetector with a 4.57 mm active diameter and a <30 ns rise time. 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. This detector comes with a 24 VDC external power supply. It includes a 50 ohm BNC connector output. It is a low-cost solution for ultra-fast measurements up to a 25 MHz bandwidth. This detectors are suitable for applications where detector rise time of <30 nsec 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.
