Product Details

Light Guide Adapters are required to mate the low profile Fiber Optic Line Lights with fiber optic illuminators.

High Contrast, Silhouetted Images
Highly Diffuse, Even Light Distribution
Ideal for Line Scan Camera Applications
Used in 2D Vision Systems

Backlighting is a machine vision lighting method that provides a high contrast silhouette of a part or part segment. The object appears black against a uniform white background. Backlights can also be used with color filters, placed at the illuminator input end, to improve the contrast of colored components. Area backlights work well with 2D vision systems. Light guide adapters needed to mate with fiber optic illuminators.
