Engrave better and faster with OMTech's ultra-high transmittance focus lens!

Manufactured from high-quality physical vapor deposition zinc selenium, our new generation of CO2 laser focus lenses offers peak optical performance. Strongly antireflective coatings on both sides give our industry-leading lenses a light transmittance rate better than 99.5% for infrared laser light at the critical wavelength of 10.6 microns. To ensure the longest service life, the coating on both sides of the lens also helps it resist scratches and other damage. The unique positive meniscus shape of our lens keeps things easy as you install it into your laser engraving machine.

With OMTech's brand-new focus lens, your laser engraving, cutting, etching, and marking work has never been easier!
