Laser Research Optics offers CO2 laser lenses for cutting heavy steel parts

Laser Research Optics offers CO2 focusing lenses designed for 10.6-µm, 200-W to 400-kW lasers used for cutting heavy steel parts. They come in OD sizes from 1 to 2.5 in. with focal lengths from 5 to 10 in., in 0.5-in. increments to match specific steel cutting requirements. Offered in plano-convex and -meniscus configurations, they can be supplied plain and mounted.

The lenses are available with A/R coatings, providing less than 0.2% total absorption, and with a proprietary Cool-Cut coating that absorbs less than 0.15% of laser energy to protect against heat damage.
