NewOpto offers Photodiode Amplifier, which is designed to provide a direct digital readout of the current generated from a photodiode, photomultiplier, or similar current source. By adjusting the A / W setting on the amplifier to equal detector responsivity, the amplifier can measure the incident optical power. The photodiode amplifier has special in function as optical power meter, full Scale Input Range of ±20nA to ±20mA, variable bias selectable from -14V to +14V, LCD display, RS-232 serial interface.
