FPD610
(High Sensitivity Fast PIN Photodetector)
The high sensitivity ultrafast PIN photodetector FPD610 product family combines broad bandwidth and high gain at frequencies up to 600 MHz.
These photodetectors are easy-to-use Si- or InGaAs-PIN photodiode packages with an integrated high-gain, low-noise transimpedance amplifier.
The 3 dB bandwidth of the DC-coupled device is 500 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.
