The 36 inch long, Visual Optic (VO) style product is a variation of the universal style glass light with interchangeable adapters on the light source end. The working or distal end is fixed to the light guide with a custom 2 inch long by 1/16 inch diameter ferrule designed to focus the light to a specific target.

It is extremely lightweight making it perfect for repetitive tasks where a borescope is not required and a flashlight is too large and cumbersome. Other variations on the distal end are available either standard or upon request.
