Laser Research Optics introduced a line of laser lenses and mirrors offered in various focal lengths to match specific steel cutting requirements. The lenses and mirrors are optimized for 10.6-micron, 200-W to 4-kW CO2 cutting lasers, come in plano-convex and meniscus configurations, and can be supplied plain or mounted. They are offered in 1-in. to 2-in. OD sizes with thicknesses ranging from 0.250 in. to 0.380 in. and feature focal lengths from 3 in. to 10 in. in 0.5-in. increments.
