CNC polished precision aspherical lenses are designed for diffraction-limited performance. We offer convex - aspherical lenses made of Suprasil specially designed to have the best performance and the highest laser induced damage threshold. The standard lenses can be supplied uncoated or anti-reflective coated at 1000-1080nm. Other coating regions are available according the request.
