Flat Top Holographic Diffuser Sets
Flat Top Holographic Diffuser Sets shape input beams to have non-Gaussian, flat top output profiles in circular, square, rectangular, and linear beam patterns. These sets feature eight 10 x 10mm active areas on a single substrate, each with a different diffusion shape and angle. A small angle set, with diffusion angles from 1 - 10°, and a large angle set, with diffusion angles from 11 - 65° are available. Flat Top Holographic Diffuser Sets are ideal for use in machine vision, LiDAR, heads up displays (HUDs), and 3D sensing applications to produce illumination with even intensity.
Unlike many holographic elements, these specific polycarbonate components transmit light in both the visible and near-infrared. Zero order, or a specular component, of transmitted light is less than 1% for visible wavelengths, but may be higher if these diffusers are used at wavelengths >700nm.
