Optical responsivity
Responsivity measures the input–output gain of a detector system. In the specific case of a photodetector, it measures the electrical output per optical input. A photodetector's responsivity is usually expressed in units of amperes or volts per watt of incident radiant power. For a system that responds linearly to its input, there is a unique responsivity. For nonlinear systems, the responsivity is the local slope. Many common photodetectors respond lin… Webmaterials purchased from Optical Procurement Services (OPS), the lab processing arm of our business.
