(Source: Laser Research Optics)Laser Research Optics of Providence, R.I., now offers a line of carbon dioxide laser optics optimized for cutting and etching thin metals when fabricating filters, strainers and related applications.

The products include lenses that feature coatings with less than 0.2% total absorption values to keep them cooler, and silicon turning mirrors which have an enhanced DMBR coating to provide up to 99.6% reflectivity. Optimized for 10.6 microns, they are designed to promote sharper cuts with fewer passes when cutting and etching thin metals.

The lenses are suited for OEMs or as field replacements for end-users, and are available off-the-shelf in 0.5 to 1.5 in. diameter sizes with focal lengths from 1.0 in. to 25 in. in 0.5 in. increments. The silicon silver DMBR coated turning mirrors come in 0.75 in. to 3.0 in. dia. sizes from 2 to 10 mm thick. All meet ISO-10110 specifications for optical elements.
