As you engrave, debris such as smoke and dust land on your focal lens, building up a layer of residue over time that absorbs laser beam power and can stain the lens 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.\u003c\/span\u003e\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003ePackage Includes:\u003c\/b\u003e\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003e1 x CVD ZnSe Focus Lens\u003c\/span\u003e\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eWarranty:\u003c\/b\u003e\u003c\/p\u003e \u003cul data-mce-fragment=\"1\"\u003e \u003cli style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003e\u003cspan style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003eNo need to worry!
