功能

• The frosted diffuser diffuses incident light over a very wide area, smoothing the luminance distribution of the original light source.
• It can be used to prevent the filament of the light source from forming, to increase the illumination range of directional illumination, or as a screen.
• The abrasive surface is rubbed with fine sand to form a rubbed glass.
• The larger the number (#), the smaller the diameter of the sand particles.
• There is a BK7 type for the visible to near-infrared range and a synthetic quartz type that can also use the ultraviolet range.
• * When using it as a screen, let it enter from the sand side.
• * If the image is incident from the back side, 4% reflection of the back side will cause ghosting of the image formation.
