Luminit’s high-temperature hybrid-glass Light Shaping Diffuser is available in circular and elliptical diffusion angles as high as 80 degrees. Rated for high damage threshold and high-temperature applications, this glass diffuser is extremely effective on Vertical-Cavity Surface-Emitting Lasers and can be designed directly into projection systems to provide precise viewing angles with high transmission efficiencies. Luminit high temperatures light shaping diffusers use a holographically recorded, randomized surface relief structure that is replicated in a layer on the surface of a UV silica or B270 substrate. The precise surface relief structures of these glass-on-glass VCSEL diffusers provide high transmission efficiency (up to 92%) and controlled beam angle divergence while providing high quality homogenized light.
