By combining state of the art photodiodes with the proven and outstanding FEMTO LCA Current Amplifier technology we designed a new family of photoreceivers with a remarkable performance. The LCA-S-400K is available with either a large area Si or InGaAs photodiode covering a spectral range from 400 to 1100 nm and 900 to 1700 nm, respectively. The amplifier transimpedance is 107 V/A resulting in a maximum conversion gain of 9.5 x 106 V/W at 1550 nm for the InGaAs model.
Due to the low noise performance of the transimpedance amplifier the minimum NEP is as low as 75 fW/√Hz which allows for detection of optical signals in the nanoWatt range without further averaging.

Threaded M4 and 8-32 mounting holes for use with standard mounting posts. Power supply ±15 V via 3-pin Lemo® socket. A mating connector is provided with the device. Optional power supply PS-15 available. For further information please view the datasheet or contact FEMTO.
The DHPVA voltage amplifier series has been revised, resulting in the new models DHPVA-101 (DC - 100 MHz) and DHPVA-201 (DC - 200 MHz). Input voltage drift and noise are improved to an extraordinary low level while still convincing with a constant bandwidth at any gain setting.
The photoreceiver series HSA-X-S was broadened by two models featuring an improvement in noise performance of up to 40%. The output reflection coefficient was reduced by 8 dB at the same time.
