The 36-inch long Visual Optic (VO) style product is a universal style glass light variation 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 concentrated light at a specific target.

It is incredibly lightweight, perfect for repetitive tasks where a borescope is unecessary and a flashlight may be too large and cumbersome. Other variations on the distal end are available either standard or upon request.
