Laser is ideal for display application because of monochrome, small divergence angle and high brightness. However,monochrome causes speckle problem due to interference and laser display needs surface light source
Traditional methods uses grinded glass for laser homogenization, which suffers from low transparency, rough spot edge and large diffusion angle(usually>30degree).This makes grinded glass only suitable for research rather than production application. We provide quartz diffuser which can solve the above problems: laser homogenization with customer-demanded diffusion angle, sharp spot edge, high transparency, excellent thermal stability for high power laser application, great improvement for speckle reduction by rotation and displacement.
