Multi-Wavelength Solutions


Many applications require wavelength-switchable sources. For example, in vision applications different types of objects may require different illumination wavelengths for optimized contrast. Mightex WheeLEDTM wavelength-switchable LED sources let users manually switch between a selection of LED sources with different wavelengths and/or white LED’s.

A wide range of wavelengths and white LED’s are available for users to choose from. The selected LEDs are installed in the light source chassis in the factory. Users can then switch among the installed LEDs by manually turning a hand wheel.

The light source includes a 5-ft electrical cable with a connector on one end to be plugged into the light source, and two bare-wire terminals at the other end. The light sources can be driven by Mightex LED controllers or other LED controllers and current sources. Only a single driving channel is required because at any time only one wavelength is powered up. Over-current protection is built into the light source to prevent potential damage during switching.
