Circular and Linear Engineered Diffuser Standard Stamps

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.
