Square Core Optical Fibers suit material processing/astronomy.
April 16, 2010 -
Non-circular core silica optical fibers offer good image scrambling and low focal ratio degradation to improve image processing. When used with diode lasers that give square-shaped output, fibers provide homogeneous power distribution on output end. Square output beam reduces need for beam shaping optics. Products are available with square cores with edge lengths from 50-1,000 microns and wavelengths from deep UV to NIR.

CeramOptec Introduces Non-Circular Core Silica Optical Fibers
East Longmeadow, MA - CeramOptec Industries, Inc., a worldwide leader in the manufacture of specialty optical fibers, bundles and assemblies, has introduced non-circular core silica optical fibers for use in applications including material processing and astronomy.
In astronomy a star is tracked over time with the spectrum being transmitted to a spectrometer. A square fiber offers a more stable means of transmission than that of a circular core fiber as the spatial power distribution is more constant. Good image scrambling is characteristic of the square core fiber and together with its low focal ratio degradation (FRD) improves image processing making them ideal for astronomy applications.
When used with diode lasers which give a square-shaped output, the square core fibers offer greater coupling efficiencies and a very homogeneous power distribution on the output end. In laser applications such as surface pre-treatment, materials 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.
CeramOptec's non-circular core silica optical fibers are available with square cores with edge lengths from 50 to 1000 microns in NA's from 0.12 to 0.37 and wavelengths from deep UV to NIR. Other shapes are available upon request.
