Product Description

Luna’s Log Detector is a useful photodiode amplifier designed to measure low light levels, down to - 90 dBm and produce linear logarithmic electrical signal. It come with two of four channel options. The LPD 100 is particularly suited to perform high dynamic range power measurements in closed loop related applications. For example, in polarization tracking, specifically when trying to track to a minimum light level, where generating a reliable tracker feedback signal could be a challenging problem.
