Contamination is a Dirty Word
Cleaning optical elements improves performance, providing proper materials, techniques and handling procedures are used to minimize the risk of damage. If you wear glasses or drive a car you know the detrimental effects of dirt on the performance of a lens or window. The effects can be more serious in optical setups that involve laser radiation. Contaminants, whether on a coating or on the substrate surface, absorb laser energy and can damage the coating or its interface with the substrate....
