3PCS FAHKNS Molybdenum Reflective Lens Dia:25mm/0.98" T3mm Mo Mirror Laser Lens for CO2 Laser Engraving Cutting Engraver/Cutter 40W-200W

[MAIN PARAMETERS]: Diameter:25mm/0.98", Thickness:3mm/0.118" [HIGH TEMPERATURE AND CORROSION RESISTANCE]: High Quality Molybdenum material,applicable power up to 40W-200W, has a high surface strength, high melting point, chemically stable high temperature and corrosion resistance, and it can be used with various laser engraving machines, etching machines, marking machines and cutting machines. [SCRUB RESISTANT, LONG LIFE]: Metal molybdenum polished directly to a mirror finish, no coating layer on the surface, scrub resistant,have a long life ,It reflects over 98% of infrared light at the critical 10600 nm wavelength, minimising power loss from the laser tube to the worktop. [INSTALLATION GUIDE]:Normally,A laser machine needs 1 focal lens ang 3 reflective lenses [APPLICATION]: Laser lenses with focal lengths of 25.4 mm, 38.1 mm and 50.8 mm are suitable for engraving. If used for cutting, we recommend working with laser lenses with a focal length of 63.5/76.2/101.6/127mm.
