Beschreibung

The high sensitivity ultrafast PIN photodetector FPD510 product family is optimized for highest signal-to-noise-ratio for detection of low level optical beat signals and pulse shape at frequencies up to 250 MHz. These photodetectors are easy-to-use InGaAs-PIN photodiode packages with an integrated high-gain, low-noise transimpedance amplifier.

The 3 dB bandwidth of the DC-coupled device is 200 MHz.

Models for both visible and near infrared range are available, both with either free space or fiber coupled optical input. The compact design of these detectors allows for easy OEM integration. Included with each amplified photodetector is a low noise power supply, which features a universal AC input.

The units are especially recommended for applications e.g. in metrology and optical lock techniques when homodyne or heterodyne optical beat signals of weak power have to be detected and amplified in a highly efficient way.
