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.
