Optical diffuser BP/SN series

for LEDs

Surface relief diffusive microstructures (SRDM) are used for specifically distributing light in a defined angle range. They homogenize irregular light distributions as well as local intensity peaks. We offer a variety of standard designs as well as custom designs for our customers. It is also possible to apply those diffusive microstructures directly into the plano side of all our plastic optics components. ___________________________________________________________________________ All dimensions in mm. The standard material used is PMMA (refractive index = 1.49; relative dispersion = 58). Other materials are available. The outside size may be up to 5 - 20mm beyond the clear aperture. Other dimensions or special trimmings can be realized uponrequest. The standard thickness is 1.8mm ± 0.3. Other thicknesses (≥0.8mm are possible) Other dimensions or special trimmings can be realised upon request. Special designs possible on request.
