Optical glass diffusers and screens diffuse the incoming light and reduce directionality in the beam. They are made in ground glasses and flashed opal glass in a range of thicknesses and finishes.

Optical Glass Diffusers

The ground glass is useful for focusing screens and weak diffusion illumination systems. It is ideal for rear protection and a variety of optical and illumination applications. One surface is diffused ground to degrees of roughness from a very find particle compound (calcite alumina) to extreme diffusing using a 120 course grit size (grades of diffusing can be selected). Materials depend on the application but generally include borosilicates, float glass, fused quartz, fused silica and optical glasses.

Flashed Opal Diffusers

Flashed opal glass have one surface flashed with a “white” opal coating 0.45mm thick (+0.35/-0.20) . It can produce near lambertian source, diffusing light thoroughly with a high amount of scattering loss. This makes them ideal when intense diffusions is needed. The material is made in standard sheets which can be cut to custom sizes see processing for details.

Opal glass diffusers are typically used in light boxes, illumination systems, cameras, instrumentation, monitors and displays.
