These air-spaced focusing lenses are manufactured from synthetic fused silica. They are optimized for use in the region 180 to 400nm making them ideal for use with excimer lasers or other ultraviolet sources. In air-spaced doublets the air gap acts as a third lens element providing a greater degree of correction. In this way it is possible to minimize all of the paraxial aberrations for the highest possible performance. As a result, these very simple lenses provide excellent performance for focusing, imaging and light collection. Focal lengths from 50 to 300mm are available with clear apertures from 27 to 47mm. These lenses are supplied uncoated and mounted in metal cells with a plain outer barrel. A range of excimer laser anti-reflection coatings may be added.
