RS-7 WavemonTM Multi-channel photodiode system with amplitude feedback and real-time wavelength measurement
The Wavelength Monitor System is a multi-channel photodiode system which provides amplitude feedback and real-time wavelength measurements. It consists of three photodiodes each with an independent transimpedance amplifier circuit. Proprietary optical filtering techniques allows for wavelength accuracy of +/-0.25nm and repeatability of +/-0.05nm. The Wavelength Monitor PCBA, photodiodes, and optical filter assembly is temperature stabilized using a Peltier cooler and thermistor in a PID feedback loop. This assembly is a discrete module which can be used with any RS-7 model.
