CeramOptec’s® non circular core silica optical fibers show the same exceptional performance and transmission as Optran UV/WF fibers with circular core geometry. With its good image scrambling and low focal ratio degradation it is ideal for astronomy applications. When used with diode lasers which give a square shaped output, the square core fibers offer greater coupling efficiencies than circular fibers. In laser applications such as surface pre-treatment, material can be processed in a more uniform fashion than is possible with a circular beam due to less overlapping. The square output beam reduces the need for beam shaping optics.
