Electro Optical Components, Inc. Low Noise Photoreceivers LCA-S-400K

By combining state of the art Si and InGaAs 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 1050 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.
