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.
