ELECTRONICS: 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.
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 inch dia. sizes with ±0.005 inch CT and feature focal lengths from 5 to 30 inches with ±0.5 percent tolerance.
Offered with A/R coatings that typically provide 0.5 percent maximum reflectance per surface at 10.6µm and normal AOI, Laser Research CO2 Cylindrical Lenses have a 60-40 scratch-dig surface finish and 1 fringe surface accuracy at 633nm. Centration error on these ZnSe lenses is 5 Arc-mins. maximum.
Laser Research CO2 Cylindrical Lenses are priced according to configuration and quantity. Price quotations are available upon request.
