Maintain beam collimation between a CO2 laser and the final focusing optics in a system with our long focal-length lenses and mirrors.
These plano-convex lenses are made from Coherent ZnSe and fabricated to deliver high transmitted wavefront quality, low absorption, and minimal scatter. The copper reflectors are available with both convex and concave radii, as well as water cooling.
Collimating Optics Selection
Choose plano-convex ZnSe lenses with focal lengths from 710 mm to 1500 mm, and spherical copper reflectors with radii from 1 to 3 m convex, and -1.68 m to -15 m concave.
