Linear and Circular Engineered Diffusers

NIL Technology offers standard engineered diffuser stamps. Engineered diffusers control light output of lighting elements and light sources like lasers, LEDs, light fixtures and blacklight units for LCDs. Engineered diffusers are surface diffusers with a very high transmission efficiency. Upon request NILT also offers customer specified, tailor-made engineered diffusers with precise diffusion control and linear, elliptical and circular diffusion profiles.

The engineered diffuser standard stamps were specifically designed as a set of multi-purpose engineered diffusers for R&D work, as well as for product and process development.

The standard engineered diffuser stamps can be delivered with or without anti-sticking coating.

Note that the standard engineered diffuser stamps are only for test and product development
purposes. A commercial use of the standard engineered diffuser stamps requires a royalty
agreement.
