5 March 2015 Improved deep UV fiber for medical and spectroscopy applications
Author Affiliations +
An effort to demonstrate long term transmission stability in a high –OH synthetic fused silica step index multimode optical fiber optimized for Deep-UV operation, designated as FDP, was successfully completed at Polymicro Technologies. The development achieved significant improvement in long term stability for the 214 and 265nm absorption bands typically associated with solarization effects in fused silica. The improvements were applied to fiber core sizes from 67 to 100µm, a common size range for bundle applications used in medical and spectroscopy. Results of UV degradation measurements for the fiber with minimum 70 hour exposures are presented along with a description of the test protocols.
