Surface Relief Diffusive Microstructures

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.

It is also possible to apply those diffusive microstructures directly into the plano side of all our plastic optics components.
