The Focal Length is the Distance Between the\nFocal Lens and the Cutting\/Engrave Material. When install the Lens, Make Sure\nthe Focusing Lens: Convex Face to Laser, Concave Face to Material. How to\nClean Laser Lens and Mirrors? Step 1 Cleaning for Light Contamination (dust,\nlint particles) Use an air bulb to blow off any loose contaminants from the\noptic surface before proceeding to the cleaning steps. Step 2 Cleaning for\nLight Contamination (smudges, fingerprints) Lay the lens tissue on the optic's\nsurface. Using an eyedropper, squeeze a few drops of acetone onto the lens\ntissue, wetting the complete optic's diameter. Without lifting the lens\ntissue, drag the lens tissue across the optic just fast enough so that the\nliquid evaporates behind the tissue. This should leave no streaks. Step 3\nCleaning for Moderate Contamination (spittle, oils) Dampen an unused cotton\nswab or cotton ball with white distilled vinegar. Using light pressure, wipe\nthe optic's surface with the damp cotton. Wipe excess distilled vinegar with a\nclean dry cotton swab. Immediately dampen a cotton swab or cotton ball with\nacetone. Gengly wipe the optic's surface to remove any acetic acid.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eDiameter: 18mm\/0.71\"; Focal Length: 25.4mm\/1\"; Thickness: 2.2mm\/0.09\"; Weight: 0.1KG\u003c\/li\u003e\n         \u003cli\u003eShape: Plano-Convex; Transmittance: 99.5%\u003c\/li\u003e\n         \u003cli\u003eMaterial: PVD Znse; Compatible power: 30W-100W\u003c\/li\u003e\n         \u003cli\u003eHigh QualitySuperb double-sided solid coating.
