Product Family Description

Diffusing Angles Ranging from 0.5 - 50°
Fused Silica Substrate Offers 70% Transmission at 200nm
Homogenous Light Distribution
Standard Holographic Diffusers Also Available

Holographic Diffusers are used to control the diffuse area of illumination and increase transmission efficiency to greater than 90% from filament lamps, LEDs, arc lamps, and other sources. These Holographic UV Diffusers use a fused silica substrate and offer controlled, homogenous light distribution from the UV through the near-infrared spectra, with transmission levels of 70% at 200nm. It is important to note that diffusing angles are given for a collimated input beam and angular divergence will vary for different incidence angles.

Note: Matte surface should face the light source.
