Photoreceivers

Femtowatt (ultra low noise min. NEP 0.7fW/√Hz), variable gain (10E3 to 10E11 V/W) and fixed gain photoreceivers offer a solution to measuring fast and precise small optical signals. By combining a low noise transimpedance amplifier with a silicon or InGaAs photodiode a broad wavelength range from 190nm up to 1700nm is covered. Ideal for all lab scenarios, fibre alignment, fast power monitoring, testing laser diodes, linearity measurements over 10 decades, and industrial control and aligment are just a few applications.

Photoreceiver Series LCA-S-400K

Low-noise photoreceivers based on the LCA series for up to 400 KHz

Photoreceivers

By combining state of the art photodiodes with the proven and outstanding FEMTO LCA Current Amplifier technology a new family of photoreceivers with remarkable performance have been designed. 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 10^7 V/A resulting in a maximum conversion gain of 9.5 x 10^6 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.

Applications include spectroscopy, general purpose opto-electronic measurements, optical front-end for Oscilloscopes.
