Cutting Edge Features: PRECISION MIRRORS: OMTech's new generation of molybdenum engraving mirrors are 20mm across and 3mm thick, offering λ/2 flatness with better than 95% clear aperture and centration under three arc minutes for exceptional optical performance. COMPLETE: This set of 3 premium molybdenum mirrors allows you to change all the used mirrors in your laser cutting machine at once, so you can keep your laser beaming at full potential. HIGH REFLECTIVITY: Specially engineered and polished to achieve more than 98% reflectivity of infrared light at the critical 10600nm wavelength, these mirrors minimize power loss in transmission from tube to workbed. LASTING DURABILITY: Our laser mirrors' molybdenum construction provides superior scratch resistance, ensuring safe polishing and longer service life. WIDE COMPATIBILITY: These high-transmittance mirrors offer superior heat resistance to work with a wide range of laser engravers, etchers, markers, and cutters from K40 desktop engravers to powerful 200W industrial engraving equipment. Specifications: Material: Molybdenum Rec. Laser Power: 30W-200W Rec. Laser Wavelength: 10.6 μm (10600 nm) Min. Reflectivity: 98% Diameter: 20mm (±0.13mm) / 25mm (±0.1mm) Thickness: 3mm (±0.25mm) Max. Centration: 3 arc min. Min. Clear Aperture: 95% Surface Flatness: λ/2 Scratch/Dig: 40/20 Net Weight: 1.1 oz (30g) Package Includes: 3 x Molybdenum Engraving Mirrors Warranty: No need to worry! We offer a 1-year warranty on all mirror sets. Certifications: FDA Compliant CE Certification ISO9001 Quality Certification Summary: It is all smoke and mirrors! As you engrave, debris such as smoke and dust land on your mirrors, building up a layer of residue over time that absorbs laser beam power and can stain the mirrors permanently. Eventually, this lost power will affect your machine’s precision and throw off your laser settings. To keep your device running at its full potential, we recommend inspecting and cleaning the optics system once a week and replacing the mirrors or focal lens as soon they get damaged.
