Abstract
A cold coupling apparatus for receiving light from a source of illumination and transmission to the ends of one or more light-guiding fibers comprises a coupler body having an exit bore, an inner bore, an entry bore, and body threads, the exit bore and inner bore intersecting to form a lens shelf, and the entry bore and inner bore intersecting to form a fiber shelf; one or more lenses disposed within the exit bore and proximate to the lens shelf; a compression fitting threadedly engaged with the body threads; a collet disposed within the compression fitting; and one or more ferrules, each of the ferrules disposed within the entry bore and proximate to the fiber shelf. A bushing may also be disposed within the compression fitting, and the lenses may be coated to reflect infrared and/or ultraviolet radiation. The coupler body may be actively cooled, or may have heat sink fins attached to its exterior.
