The 818-BB-21A 1.2 Ghz Optical Reciever consists of a free-space 300 to 1100 nm biased Silicon detector with a 0.40 mm diameter and a 500 ps rise time. It has a built-in amplifier with 26 dB of gain. It is excellent for viewing rapid modulation of low-power CW lasers or other light sources in the &mu,W regime. The detector is AC coupled and features a bandwidth of up to 1.2 GHz. A wall plug-in style power supply is provided with this unit. 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.
