The 818-BB-45 High Speed GaAs Detector consists of a free-space 500 to 890 nm battery biased GaAs photodetector with a 60 µm active diameter and a <30 ps rise time. It includes a built-in bias supply consisting of one standard 3V lithium cells and a SMA connector output. 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.
The 818-BB-45 high speed optical detector consists of free-space 40 µm diameter GaAs photodetector, with a 30 ps rise time and 12.5 GHz bandwidth. It includes a built-in bias supply consisting of single 3 V lithium cell 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.
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.
The 818-BB-35 and 818-BB-45 photodiode detector modules offer a low-cost solution for ultra-fast measurements offering a 12.5 GHz bandwidth. These detectors are suitable for applications where detector rise time of <25 ps (<30 ps for 818-BB-45) are required for Q-switched and Ultrafast Laser output analysis. These detectors also utilize 3 V lithium cells (supplied).
