· Frost type diffusion plates diffuse irradiated light over an extremely wide range and are effective in smoothing the luminance distribution of the original light source.
· Also usable to prevent image formation of the light source filament, to enlarge the irradiation range of directive lighting, and as a screen.
· This element has a frosted glass-like finish which is achieved by scrubbing the polished face with fine grains of sand.
· The diameter of the sand particle gets finer as the numeral for the sand number (#) gets larger.
· BK7 type for visible range to near infrared range and synthetic quartz type that can also be used for ultraviolet range are available.
· * When using as a screen, incidence should occur from the sanded surface side.
· * If light enters from the back side, ghosting is generated in the image via the 4% reflection on the back side.
