RS-7-6 Wide Field of View

The SpectralLED® Wide Field of View (FOV) uniform light source is ideally suited for applications requiring a field of view up to 180°. The unique optical design delivers equal radiance over the entire field, with better than 97% uniformity across the 75mm output. The SpectralLED® Tunable Light Source incorporates up to 35 discrete wavelengths for synthesis of commercially available light sources or based on spectra that you import. The platform is easily adaptable for automated test systems and production line integration, with integrated optical feedback and temperature control to ensure rock-solid stability and consistent results.

Specifications are subject to change without notice

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.
