A line of ZnSe cylindrical lenses that focus light into one dimension only and are available in a variety of focal lengths and configurations has been introduced by Laser Research Optics of Providence, Rhode Island.
Laser Research CO2 Cylindrical Lenses are designed to produce astigmatism, stretching a 10.6 µm laser beam into a line shape and are offered with antireflective coatings to increase the light transmission. Featuring focal lengths from 5” to 30”, with ±0.5% tolerance, these lenses provide
a 40-20 scratch-dig surface finish and 1 fringe surface accuracy @633 nm.
Available in sizes from 1” to 2” dia. with ±0.005” CT, Laser Research CO2 Cylindrical Lenses are offered round or square with +0.000”-0.010” tolerance and a light protective bevel. Centration error on these ZnSe lenses is 5 Arc-mins. max. The antireflective coating typically provides 0.5% max. reflectance per surface at 10.6 µm and normal AOI.
Laser Research CO2 Cylindrical Lenses are priced according to configuration and quantity. These products will be on exhibit at "FABTECH International"" November 11 to 14, 2007, McCormick Place, Chicago, Booth 8033.
