High-Volume, Low-Cost Light Shaping Diffusers for Laser Projection Systems

Luminit’s Monolithic Glass Light Shaping Diffusers (MG-LSD) improve the beam angle quality of light engines and reduce speckle in laser-based projectors. Available in angles from 1° up to 15°, these glass plate diffusers are etched directly into float glass and can be mass produced at a low per piece cost.  This glass diffuser has a high laser damage threshold and light transmission up to 98% with optional AR coating.
