Product Details
Product Model: 61-6881-67
Product Brand: SIGMAKOKI CO., LTD.
Features
- The frosted diff***r diff***s incident light over a very wide area, smoothing the luminance distribution of the original light source.
- It can be ***d 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 *** 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 ca*** ghosting of the image formation.
