Excimer Laser Focusing Lenses

These synthetic fused silica, air-spaced focussing lenses are optimised for the region from 180nm to 400nm. They are ideal for use with excimer lasers or other ultraviolet sources. In an air-spaced doublet, the air gap acts as a third lens element and provides a greater degree of correction. This makes it possible to minimise all of the paraxial aberrations and gain the highest possible performance. As a result, these simple excimer laser lenses have excellent performance in focusing, imaging and light collection. Focal lengths are available from 40 to 300mm, with clear apertures from 27mm to 47mm. The lens is uncoated and comes mounted in a metal cell with a plain outer barrel.
