A dirty mirror costs a few percent. A mirror with a poor coating costs far more, and the loss shows up as slow cuts, charred edges and a tube working harder than it should. This silicon reflector is specified at 99.6% reflectivity with a black coating on the back face, which is the combination that keeps delivered power high and stray reflections low.\u003c\/p\u003e\n  \u003cp\u003eThe substrate is silicon rather than glass, which matters for two reasons. Silicon holds its flatness under heat, so the beam does not wander as the mirror warms during a long job. It also takes the dielectric coating more evenly, which is where the reflectivity figure comes from. The black-coated back face absorbs rather than reflects, so light that passes the coating does not bounce back into the cavity and disturb the beam.\u003c\/p\u003e\n  \u003cp\u003eThe mirror is sized for standard 500W-class CO2 installations and fits the common mirror mounts used on Chinese and imported laser cutters. Handling matters: the coated face should never be touched, and cleaning is done with a lens tissue and approved solvent rather than a cloth. Replacing all three mirrors in a beam path at once is the standard practice, because a new mirror next to a worn one simply moves the loss to the older surface.\u003c\/p\u003e\n  \u003cp style=\"font-style:italic;color:#555;border-left:3px solid #c9a86a;padding-left:14px;margin-top:18px;\"\u003eOptics are the cheapest part of a laser and the most expensive thing to neglect.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr style=\"margin:26px 0;border:0;border-top:1px solid #ececec;\"\u003e\n\u003cdiv class=\"product-features\"\u003e\n  \u003ch3 style=\"margin-bottom:10px;\"\u003eWhat Sets It Apart\u003c\/h3\u003e\n  \u003cul style=\"list-style:none;padding:0;margin:0;font-size:15px;line-height:1.7;\"\u003e\n    \u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cspan style=\"color:#8a6d3b;margin-right:8px;\"\u003e✦\u003c\/span\u003e99.6% reflectivity silicon substrate for minimal power loss per bounce\u003c\/li\u003e\n    \u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cspan style=\"color:#8a6d3b;margin-right:8px;\"\u003e✦\u003c\/span\u003eBlack-coated back face to absorb rather than reflect stray light\u003c\/li\u003e\n    \u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cspan style=\"color:#8a6d3b;margin-right:8px;\"\u003e✦\u003c\/span\u003eSilicon holds flatness under thermal load, keeping the beam stable during long jobs\u003c\/li\u003e\n    \u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cspan style=\"color:#8a6d3b;margin-right:8px;\"\u003e✦\u003c\/span\u003eDielectric coating applied evenly across the aperture\u003c\/li\u003e\n    \u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cspan style=\"color:#8a6d3b;margin-right:8px;\"\u003e✦\u003c\/span\u003eFits standard 500W-class CO2 mirror mounts\u003c\/li\u003e\n    \u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cspan style=\"color:#8a6d3b;margin-right:8px;\"\u003e✦\u003c\/span\u003eCompatible with common imported and domestic laser cutter heads\u003c\/li\u003e\n    \u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cspan style=\"color:#8a6d3b;margin-right:8px;\"\u003e✦\u003c\/span\u003eSupplied individually packed to protect the coated surface in transit\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-specs\"\u003e\n  \u003ch3 style=\"margin:26px 0 10px;\"\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003cul style=\"list-style:none;padding:0;margin:0;font-size:15px;line-height:1.7;\"\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eSubstrate:\u003c\/strong\u003e Silicon (Si)\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eReflectivity:\u003c\/strong\u003e 99.6%\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eBack coating:\u003c\/strong\u003e Black absorbing coating\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eLaser type:\u003c\/strong\u003e CO2, 500W class\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eMount:\u003c\/strong\u003e Standard CO2 mirror mount\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eSurface:\u003c\/strong\u003e Dielectric coated, do not touch\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eCleaning:\u003c\/strong\u003e Lens tissue with approved solvent only\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Beam delivery optics in CO2 laser cutters and engravers\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eReplacement practice:\u003c\/strong\u003e Replace all mirrors in the beam path together\u003c\/li\u003e\n    \u003cli style=\"padding:8px 0;border-bottom:1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003ePacking:\u003c\/strong\u003e Individually packed, coated face protected\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-applications\"\u003e\n  \u003ch3 style=\"margin:26px 0 10px;\"\u003eWhere It Belongs\u003c\/h3\u003e\n  \u003cp\u003eFor laser cutter owners doing maintenance on a machine that has lost cutting power, and for anyone assembling or rebuilding a beam path.
