Similar to ground glass, but with one surface flashed with a milky white "opal" coating to diffuse light evenly. Opal Diffusing Glass can be used to achieve a near Lambertian distribution. The level of diffusion in opal glass causes a large amount of scattering loss. Due to the manufacturing process of the opal coating, the transmission may vary from one production to the next.
Note: Opal Glass material has been discontinued by the manufacturer and is available in limited quantities. Please consider White Diffusing Glass as an alternative. Contact us for more information.
