For experiments requiring high bandwidths and extremely short rise times choose the Menlo Systems FPD310 photoreceiver. An easy-to-use InGaAs-PIN photodiode package with integrated high gain, low noise RF amplifier. It offers a well-balanced combination of gain, bandwidth and low noise.

The high sensitivity PIN Photo Detector FPD510 is optimized for highest signal-to-noise ratio when detecting low level optical beat signals at frequencies up to 200 MHz. The unit is recommended in particular when it comes to applications in metrology when beat signals of weak power have to be detected in a very efficient way. Models for both the visible and the near infrared regime are available.
