Newport Visible Femtowatt Photoreceiver Module
-
This battery-operated photoreceiver has high gain and detects CW light signals in the sub-picowatt to nanowatt range. When used in conjunction with a modulated light source and a lock-in amplifier to reduce the measurement bandwidth, it achieves sensitivity levels in the femtowatt range. Doric offer this Newport product with add-on fiber optic adapter that improves coupling efficiency between the large core, high NA optical fibers used in Fiber Photometry and relatively small detector area. Its output analog voltage (0-5 V) can be monitored with an oscilloscope or with a DAQ board to record the data with a computer.
