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. To clean holographic diffusers, dampen a lint free cloth wipe with methanol and gently wipe the entire diffuser surface in a gentle, circular pattern. Immediately and carefully blow off the clean diffuser area with dry compressed air. Caution: cleaning may cause a change in the optical performance of the diffuser.
