thin film optics

If you are trying to develop your own Super-Duper-Magic-and-Revolutionary light fixtures, there are five companies you might be interested in for “the good stuff”. Two supply excellent diffusion films with precision optics and transmission efficiency exceeding 90%; the other two deliver white materials with high reflectance, some over 98% reflective. Each is also progressing towards 3D shapes and other form factors using their core products in injection molds, vacuum molds, etc.

As a bonus, for innovative “remote phosphor” style lighting systems, the fifth makes YAG phosphors (the yellow colored phosphor you see on white LEDs) impregnated into flat sheets and injection-molded shapes.
