A new line of ZnSe focusing lenses for high powered lasers up to 4 kW that can be supplied with various focal lengths and coatings has been introduced.
ZnSe Focusing Lenses are available with a proprietary Cool-CutTM coating which absorbs < 0.15% of laser energy to protect against heat damage or with standard A/R coatings providing < 0.2% total absorption. Featuring focal lengths from 3” to 10” in 0.5” increments to match specific steel cutting applications, they can be supplied plain or mounted.
Offered in 1” to 2” O.D. sizes with thicknesses ranging from 0.250” to 0.380”, ZnSe Focusing Lenses are optimized for 10.6 microns and come in plano-convex and -meniscus configurations. Suited for OEMs and field-replacement by users, these CO2 lenses are ideally suited for use in steel cutting lasers ranging from 1 to 4 kW.
