#54-724 + #54-173 Light Guide

#54-724 + #54-173 Light Guide


  • 暗場照明可呈現應變與缺陷
  • 2 Aperture Sizes Available
  • Easy Snap On Attachment



Differential color illumination can be achieved by using Area Backlights and filtering the illuminator (via color filters) at the input end of the fiber optic light guide.

The darkfield attachment can only be used with ring light #54-173. The attachment conveniently snaps onto either ring light guide easily using a rubber O-Ring. This replaces the hassle of set screws and allows the Darkfield Attachment to be rotated. The window is held in place by a split ring rubber gasket and can be removed. The ring light guide requires a light guide adapter to attach to the illumination source. For proper contrast, our Light absorbing black out material is highly recommended.

Light absorbing black out material is also useful to ensure a pure black background. The black out material is available in various sizes and can be easily cut to size.

Note: Edmund Optics has lowered the prices of the Replacement Window #54-827 more than 30%! Supplies are limited! Prices shown reflect discount.
