High Sensitivity at High Bandwidth

The series HCA-S-200M Photoreceivers combine fast photodiodes with the proven and outstanding FEMTO HCA Current Amplifier technology. The HCA-S-200M-IN is available with a  InGaAs photodiode covering a spectral range from 900 to 1700 nm. The amplifier transimpedance is 2 x 10^4 V/A resulting in a maximum conversion gain of 1.9 x 10^4 V/W at 1550 nm for the InGaAs model. The sophisticated DC coupled multi-stage amplifier design allows measurements from DC to a maximum bandwidth of 200 MHz corresponding to a minimum rise-time of 1.8 ns. With a NEP as low as 5.4 pW/√Hz signals with an optical power in the micro-Watt range can be detected without the need for further averaging.

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