Ultraviolet Optics Selection Guide

Selecting the proper optic for an ultraviolet application is very important to the success of your set up. Because of the shorter wavelengths, any pits, flaws or coating impurities on the optical surface may form a concentration of optical power creating a hot spot on the optic. Depending on your application and how far you are into the Ultraviolet wavelengths, quality, cleanliness, and special packaging requirements are key considerations.

Proper manufacturing techniques and keen attention to cleanliness are required to make the best UV optics possible. If improper grinding or polishing techniques are used, there is a potential for the substrate to have higher microroughness and possible micro-fractures. The visual inspection of the substrate surfaces may look good, but when UV coatings are applied, a typical outcome is grazing or micro-fractures in the coating. Typically the blame is put on the quality of the coating but in actuality, substrate preparation is critical for good coating adherence. We, at Newport, have extensive experience in the proper manufacturing, cleanliness, coating technology, packaging and proper handling of UV optics. Look to us for solutions to your UV optics needs.
