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

OMTech's ultra-high transmittance focus lens allows for better and faster engraving. Manufactured from high-quality physical vapor deposition zinc selenium, our new generation of CO2 laser focus lenses delivers peak optical performance. Strongly antireflective coatings on both sides of the lens provide an industry-leading light transmittance rate of better than 99.5% for infrared laser light at the critical wavelength of 10.6 microns. The double-sided coating process also ensures the lens can withstand scratches and other damage, extending its service life. The unique positive meniscus shape of our lens makes it easy to install correctly 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 of high-quality CVD (chemical vapor deposition) zinc selenium, ensuring superior optical properties. Both sides of the lens are coated with strongly antireflective materials, achieving a transmittance rate of better than 99.5% for infrared light at 10.6 microns. This exceptional light transmittance rate, combined with the lens's outstanding scratch resistance, guarantees a long service life.
