Engineered diffusers (EDs) 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. NILT also offers customer specified, tailor-made engineered diffusers with precise diffusion control and linear, elliptical and circular diffusion profiles.
The ED Standard Stamp series was specifically designed as a set of multi-purpose engineered diffusers for R&D work, as well as for product and process development.
