Our secondary elliptical mirrors are made from high quality low expansion glass with enhanced aluminum coatings. Before the finished side is started the backs are ground flat to a 20 micron finish. Once the main face is ground and polished into a high quality flat it is tested both before and after being coated. The minimum standard is 1/10 wave. All of our elliptical flats are coated with a three layer enhanced aluminum coating with a peak reflection of 98% in the visible spectrum. Each mirror comes with it's own interferometric data including interferogram, RMS and Peak-Valley analysis.
