Coating

Coatings are applied on each lens surface to maximize the transmission of the complete optical system like F-Theta-Ronar lenses or beam expanders. The additional challenge for coatings in laser material applications lies in a high damage resistance. All our coatings are analyzed for laser-damage threshold values. The tests are conducted according to the standardized test method DIN EN ISO 11254-2, a multi-pulse procedure (S on 1) with given pulse lengths:
