  • Integrated Low-Noise Amplifier
  • Power Supply Included

Menlo Systems' high-sensitivity Silicon (Si) PIN photodetectors are easy-to-use photodetectors with an integrated high-gain, low-noise RF (FPD310-FC-VIS) or transimpedance (FPD510-FC-VIS and FPD610-FC-VIS) amplifier. 

The FPD310-FC-VIS is optimized for high gain, high bandwidths, extremely short rise times, and high signal-to-noise ratio. The gain can be switched between two settings, which allows optimal performance for many applications. The 3 dB bandwidth of this AC-coupled device is 5 - 1000 MHz.

The FPD510-FC-VIS and FPD610-FC-VIS photodetectors are optimized for maximum signal-to-noise-ratio for detection of low-level optical beat signals and pulse shapes at frequencies up to 250 MHz and 600 MHz, respectively. Both detectors have a fixed gain. The FPD510-FC-VIS has a rise time of 2 ns, while the FPD610-FC-VIS has a 1 ns rise time. The 3 dB bandwidth of these DC-coupled devices is 200 MHz for the FPD510-FC-VIS and 500 MHz for the FPD610-FC-VIS.

The compact design of these detectors allows for easy OEM integration. These detectors feature a FC/PC input for fiber-coupled applications and include a power supply that has a universal AC input. To view Si detectors with free-space input, click here.

Hello, I have the PDA10A, but I need the photodetector which has higher bandwidth and also high gain; I came across the FPD310-FV and FDP510-FV; I could not see the transimpedance gain (V/A)in their spec compare to the spec of PDA10A; does it mean that these two detectors does not have the gain stage inside? My other question is related to this sentence given in the Overview of FPD310-FV:"This photodetector is not suitable for pulses longer than 30 ns or continuous light levels." I do need to test the pulses with the pulse width of 100 ns to 10 ns, so it means that this detector is not gonna work for me, right? Do you have any detector with the same bandwidth (around 1GHz)which also has a high gain of around 40dB? Thanks,

Response from Jeremy at Thorlabs: The gain is given at 750nm (which has a responsivity of about 0.5A/W). Therefore, the gain for setting 1 would be about 10^5 V/A and for setting 2 would be about 10^3 V/A. The FPD310-FV has a 3dB bandwidth of 10-900MHz, which is where the 30ns number come from. I will contact you directly to discuss about your application requirements.
