ZnSe Cylindrical Lenses Focus Or Expand CO2 Laser Beams
A line of ZnSe cylindrical lenses that are used to focus or expand laser beams for applications such as optical metrology, laser scanning, spectro-scopy, and laser diode systems is available from Laser Research Optics of Providence, Rhode Island.
Laser Research CO2 Cylindrical Lenses can be used to focus a laser beam into a thin line or expand the output of a laser diode into a symmetrical beam in one axis only. They are available in 1" and 2" dia. sizes with ±0.005" CT and feature focal lengths from 5" to 30" with ±0.5% tolerance.
Offered with A/R coatings that typically provide 0.5% max. reflectance per surface at 10.6 µm and normal AOI, Laser Research CO2 Cylindrical Lenses have a 60-40 scratch-dig surface finish and 1 fringe surface accuracy at 633 nm. Centration error on these ZnSe lenses is 5 Arc-mins. max.
Laser Research CO2 Cylindrical Lenses are priced according to configuration and quantity. Price quotations are available upon request.
