Edmund Optics Inc. UV Holographic Diffuser 25 Degree Diffusing Angle 25mm Dia NT48-509

Diffusing Angles Ranging from 0.5 - 50° Fused Silica Substrate Offers 70% Transmission at 190nm 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 190nm.It is important to note that diffusing angles are given for a collimated input beam and angular divergence will vary for different incidence angles.
