Photodetector by Menlo Systems

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

The FPD310-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 2 mW and 3 dB bandwidth of 5 MHz - 1000 MHz. This photodetector has a saturation limit of up to 200 μW and frequency range of 1 MHz - 1500 MHz. It has a rise time of 0.5 ns and maximum gain of 2 x 104. This photodetector has a noise equivalent power (NEP) of 12 pW/sqrt(Hz) and dark state noise level of -100 dBm/sqrt(Hz) (up to 5 MHz) & -130 dBm/sqrt(Hz) (for 5 MHz - 1500 MHz).

The FPD310-FC-NIR has two switchable gain settings: 0 dB & 20 dB attenuation and an integrated low noise radio frequency amplifier. It has an SMF28 fiber-coupled output fiber that supports FC/APC and SMA female connectors. This photodetector requires a DC supply voltage of 12 V and consumes 100 mA of current. It is available in a compact design that measures 60 mm x 50 mm x 20 mm and is ideal for detection of fast laser pulses in the near-infrared or visible range, detection of low light level signals, radio frequency & pulse shape extraction of laser light sources & heterodyne laser beat signal detection applications.
