    Optical Diffusers

    Optical Diffusers are used to evenly diffuse light in a wide variety of industrial applications. Optical Diffusers cause light to spread evenly across a surface, minimizing or removing high intensity bright spots. Optical Diffusers are also ideal for use as screens or targets in imaging applications. Optical Diffusers are also known as Light Diffusers in many illumination applications. Substrate determines the level of loss due to scatter.

    Edmund Optics offers a wide variety of Light Diffusers in a range of substrates including ground glass, holographic, or opal. TECHSPEC Ground Glass Diffusers are ideal for applications that require low scatter loss. Holographic Diffusers are used to increase transmission efficiency from a variety of light sources. UV Holographic Diffusers are also available for increased performance in the ultraviolet. Opal Diffusing Glass is ideal for generating a nearly Lambertian distribution of light, but cause higher levels of scattering loss. Optical Diffusers are available in a wide range of sizes to meet an application’s needs.
