A line of CO2 laser optics optimized for cutting and etching thin metals when fabricating filters, strainers and related applications is available from Laser Research Optics. Laser Research CO2 Optics include lenses that feature coatings with < 0.2 percent total absorption values to keep them cooler and silicon turning mirrors which have an enhanced DMBR coating to provide up to 99.6 percent reflectivity. Optimized for 10.6 microns, they promote sharper cuts with fewer passes when cutting and etching thin metals.
Suited for OEMs or as field replacements for end-users, Laser Research CO2 Lenses are available off-the-shelf in 0.5”- to 1.5”-dia. sizes with focal lengths from 1.0” to 25” in 0.5” increments and the Silicon Silver DMBR coated turning mirrors come in 0.75” to 3.0” dia. sizes from 2 to 10 mm thick. All meet ISO-10110 specifications for optical elements.

turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
