Mightex single- and multi-wavelength fiber coupled LEDs are enabled by the latest LED technologies and Mightex's proprietary beam combining/coupling optics. Up to eight (8) LEDs are coherently combined into a single multi-mode fiber with the highest efficiency practically possible. Optical output is coupled into a fiber through a standard SMA fiber adaptor port, and customers can use fibers with different core diameters with the WFC module. Each LED in the module can be powered individually or simultaneously, making the WFC-series a new class of light sources with a tunable spectrum.
