Fiber Optic Backlights

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.
