OMTech 18mm ZnSe Focus Lens for Laser Engraving Machines

Manufactured from high-quality physical vapor deposition zinc selenium, OMTech's ultra-high transmittance focus lens offers peak optical performance for better and faster engraving. Strongly antireflective coatings on both sides of the lens give it a light transmittance rate better than 99.5% for infrared laser light at the critical wavelength of 10.6 microns, ensuring the longest service life by helping it resist scratches and other damage. The unique positive meniscus shape of the 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. The lens is made from high-quality CVD ZnSe and features both sides coated with strongly antireflective coatings to achieve a better than 99.5% transmittance rate for infrared light at a wavelength of 10.6 microns. This double-sided coating process also ensures outstanding scratch resistance for a long service life.
