OMTech 18mm ZnSe Focus Lens for 50W-80W Laser Engraving Machines

Manufactured from high-quality physical vapor deposition zinc selenium, OMTech's new generation of CO2 laser focus lenses offers peak optical performance. Strongly antireflective coatings on both sides of these industry-leading lenses give them a light transmittance rate better than 99.5% for infrared laser light at the critical wavelength of 10.6 microns. This ensures the longest service life, as the coating on both sides of the lens also helps it resist scratches and other damage.

The unique positive meniscus shape of OMTech's laser focus lens keeps things easy as you install it into your engraving machine. With this brand-new focus lens, your laser engraving, cutting, etching, and marking work has never been easier!
