Laser Research Optics: Cool-Cut CO2 laser lenses

A new line of low absorption laser lenses for use with high power CO₂ lasers that are designed to run cooler than conventional A/R coated lenses is being introduced by
Laser Research Optics of Providence, RI.

Laser Research Cool-Cut CO₂ Laser Lenses are specially coated to absorb <0.15% of laser energy which protects against thermal damage and provides focal length stability to assure consistent cut quality. Developed for high power CO₂ lasers, they will last longer than standard A/R coated lenses, depending upon the application, claims the firm.

Direct replacements for popular standard OEM laser Lenses, Laser Research Cool-Cut CO₂ Laser Lenses are available in 1.5" and 2.0" dia. sizes from 0.236" to 0.380" thick with focal lengths from 1" to 25" in 0.5" increments. Surface quality is 40-20 scratch-dig and transmission is >99.0% at 10.6 µm.
