A variety of custom and select optics suit deep-UV excimer and UV-DPSS lasers and beam-delivery systems. Made from premium UV-grade fused silica, calcium fluoride, and magnesium fluoride materials, the optics are 100% lab-inspected. The multi-element imaging lenses enable users to drill and micromachine micron-scale features, and feature reportedly tighter tolerances and longer lifetimes than off-the-shelf optics.
