Fiber Coupled Dual-LED

This Fiber Coupled Dual-LED was assembled from 2 units of Microscope-LEDs connected to a Beam Combiner OptiBlock. Each Mic-LED provides a collimated beam of different wavelengths, combined into a single collinear beam by the beam combiner OptiBlock. On the exit port of the Beam Combiner OptiBlock we assembled a barrel and installed a focusing aspheric condenser lens and an optical SMA female connector. The result was a very effective coupling to both wavelengths into a single fiber. The output power of 385nm and 480nm combination was >70mW and >22mW respectively from a 1500um core Polymer Optical Fiber (POF).
