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.
Flashed opal diffusers offer better diffusion than optical glass but with a very high scattering loss. Opal diffusers come in standard sheets and can be shaped per your specifications for a quick turnaround.
