Laser Engraving Focal Lens for 50W-80W Machines

Premium Material for Exceptional Performance and Durability OMTech's laser engraver focus lenses are manufactured from first-rate chemically vapor deposited (CVD) zinc selenide (ZnSe) sourced from the USA, providing superior optical properties and an extended service life. Both surfaces of these lenses undergo a meticulous double-coating process to achieve superior transmittance of infrared light at 10.6 microns, exceeding 99.5%. This advanced coating technology also enhances the lenses' resistance to scratches and dents, ensuring lasting durability for your laser engraving and cutting machine.

Secure Packaging for Perfect Condition Each OMTech laser engraver focus lens is carefully packaged to arrive at your doorstep in perfect mint condition. The lens is nestled between layers of soft protective foam within a secure plastic case, shielding it from potential damage during shipping.

Wide Compatibility and Easy Installation This 18mm laser focus lens is compatible with 50W-80W CO2 laser engraving and cutting machines, enabling more accurate and efficient production. The plano-convex shape of the lens allows for easy and correct installation onto your machine, ensuring proper orientation.
