For coupling to UV solid-state lasers and laser diodes, SAES Getters spa produces extracavity optical components. Beam delivery from the source to the target is accomplished via collimating optics, beam expanders and f/Theta lenses, all assembled to ensure that spot size, transmission and wavefront error specifications are met. The f/Theta lenses are available with 160-, 250- and 500-mm focal lengths, with 230-, 300- and 885-mm back focal lengths and with maximum scan angles of ±22°. Beam expanders are offered in 2× and 3.5× magnifications, with input diameters of 7 and 11 mm, and with output beam diameters of 14 and 38.5 mm, respectively. Collimators are available in focal lengths of 16, 22 and 38 mm.
