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

70% Typical Illuminator Coupling Efficiency
Cool, Uniform Illumination
Crimped Stainless Steel Terminations
Ground and Polished Glass Fibers

Dual Branch Light Guides are single input dual output ground and polished glass fibers that are designed to split the output of a single illumination source. The guides have crimped stainless-steel terminations within a protective sheath. They feature 70% typical illuminator coupling efficiency and provide cool, uniform illumination. Dual Branch Light Guides require an adapter that is dependent on the tip diameter to connect to Fiber Optic Illuminators.

Note: For 1/8" fiber diameters use #38-943, and for ¼" use #38-944.
