CO2 laser lenses by Laser Research Optics run cooler for better quality cuts

Laser Research Optics, Providence, R.I., has made available a line of ultra-low absorption CO₂ laser lenses that run cooler than standard lenses to protect against thermal damage and provide focal length stability.

Laser Research Cool-Cut CO₂ Laser Lenses feature a proprietary coating that absorbs < 0.15% of laser energy to run cooler and provide focal length stability to assure consistent quality cuts. Less prone to thermal damage, they are offered in 1 to 2 inch dia. sizes from 0.236 to 0.380 inch thick with focal lengths from 1 to 25 inch in 0.5 inch increments.

Designed to run cooler and last longer than standard A/R coated lenses, these lenses are direct replacements for most standard OEM lenses. Surface quality is 40-20 scratch-dig and transmission is >99.0% at 10.6 µm.
