Laser Research Optics makes ZnSe cylindrical lenses available

Laser Research Optics, Providence, RI, has made available 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.

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 inch and 2 inch dia. sizes with ±0.005 inch CT and feature focal lengths from 5 to 30 inches with ±0.5% tolerance.

Offered with A/R coatings that typically provide 0.5% max. reflectance per surface at 10.6 micron and normal AOI, these 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.
