High Sensitivity at High Bandwidth

The series HCA-S-400M Photoreceivers combine fast photodiodes with the proven and outstanding FEMTO HCA Current Amplifier technology. The HCA-S-400M-IN is available with a fast InGaAs photodiode covering a spectral range from 900 to 1700 nm. The amplifier transimpedance is 5 x 10^3 V/A resulting in a maximum conversion gain of 4.8 x 10^3 V/W at 1550 nm. The sophisticated DC coupled multi-stage amplifier design allows measurements from DC to a maximum bandwidth of 400 MHz corresponding to a minimum rise-time of 1 ns. Due to the low-noise design signals with an optical power in the micro-Watt range can be detected without the need for further averaging. Different models with free space or fiber optic input are available.

Standard delivery time: 3 weeks ARO, Conditions: Ex.Works Germany unless specified
