Photodetector by Menlo Systems

Note: Your Quotation Request will be directed to Menlo Systems.

The FPD510-FC-NIR from Menlo Systems is an InGaAs PIN Photodetector that has a spectral range of 950 nm - 1650 nm. It has a damage threshold of 3 mW and 3 dB bandwidth of DC - 200 MHz. This photodetector has a saturation limit of up to 100 &muW and frequency range of DC - 250 MHz. It has a rise time of 2 ns and maximum gain of 1.5 x 105. This photodetector has a noise equivalent power (NEP) of 3 pW/sqrt(Hz) and dark state noise level of -110 dBm/sqrt(Hz) (up to 5 MHz) & -135 dBm/sqrt(Hz) (for 5 MHz - 250 MHz).

The FPD510-FC-NIR has an integrated low noise radio frequency amplifier and SMF28 fiber-coupled output fiber that supports FC/APC & SMA female connectors. It requires a DC supply voltage from -12 V to +12 V and consumes 20 mA - 50 mA of current. This photodetector is available in a compact design that measures 60 mm x 50 mm x 20 mm and is ideal for efficient homodyne & heterodyne extraction of optical beat signals at frequencies up to 250 Mhz, detection of low light level signals, characterization of pulsed or modulated light sources features, and detection of chopped light sources applications.
