RS-7-3 Fiber Optic Output

The SpectralLED® Fiber Optic Output configuration provides flexible illumination for applications where space is limited.

Systems can be configured with multiple outputs enabling several devices to be simultaneously illuminated at different working locations. Collimating optics are included at the fiber distal end, and custom fiber diameters and lengths are available.

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.

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.
