At the 1064 nm wavelength used by fiber lasers, lenses are typically made from high-purity fused silica with low loss anti-reflection coatings to maximize transmission and withstand high power. The three optics you\u2019ll encounter inside a typical cutting or marking head are the <strong data-start=\"563\" data-end=\"583\">collimating lens<\/strong> (which turns the diverging beam from the fiber into a parallel beam), the <strong data-start=\"658\" data-end=\"675\">focusing lens<\/strong> (which concentrates that parallel beam to a microscopic spot), and when using scan heads an <strong data-start=\"768\" data-end=\"784\">F-Theta lens<\/strong> (to keep spot size uniform across the field). Common focal lengths for focusing optics are 75, 100, 120, 150, and 200 mm; shorter f improves resolution and speed on thin sheets, while longer f increases depth of focus and process stability on thicker sections.<\/p>\r\n\r\n<h3 dir=\"ltr\" data-start=\"1052\" data-end=\"1078\">laser machine lens price<\/h3>\r\n<p dir=\"ltr\" data-start=\"1079\" data-end=\"1119\">Lens price is driven by several factors:<\/p>\r\n\r\n<ol dir=\"ltr\" data-start=\"1120\" data-end=\"1729\">\r\n \t<li data-start=\"1120\" data-end=\"1252\">\r\n<p data-start=\"1123\" data-end=\"1252\"><strong data-start=\"1123\" data-end=\"1153\">Optical substrate &amp; grade.<\/strong> High-grade fused silica with tight wavefront specs (e.g., \u03bb\/10) costs more than standard grades.<\/p>\r\n<\/li>\r\n \t<li data-start=\"1253\" data-end=\"1368\">\r\n<p data-start=\"1256\" data-end=\"1368\"><strong data-start=\"1256\" data-end=\"1269\">Coatings.<\/strong> Low-loss AR coatings optimized for 1030\u20131080 nm and contamination-resistant variants raise cost.<\/p>\r\n<\/li>\r\n \t<li data-start=\"1369\" data-end=\"1491\">\r\n<p data-start=\"1372\" data-end=\"1491\"><strong data-start=\"1372\" data-end=\"1402\">Power handling &amp; geometry.<\/strong> Larger diameter, thicker lenses with higher laser-damage thresholds (LDT) are pricier.<\/p>\r\n<\/li>\r\n \t<li data-start=\"1492\" data-end=\"1614\">\r\n<p data-start=\"1495\" data-end=\"1614\"><strong data-start=\"1495\" data-end=\"1528\">Brand and head compatibility.<\/strong> Optics matched to specific heads (Raytools, Precitec, WSX, etc.) command a premium.<\/p>\r\n<\/li>\r\n \t<li data-start=\"1615\" data-end=\"1729\">\r\n<p data-start=\"1618\" data-end=\"1729\"><strong data-start=\"1618\" data-end=\"1652\">Manufacturing tolerances &amp; QA.<\/strong> Better centration, surface quality, and clean-room packaging increase price.<\/p>\r\n<\/li>\r\n<\/ol>\r\n<p dir=\"ltr\" data-start=\"1731\" data-end=\"2067\">As a rule of thumb, F-Theta lenses (for galvo systems) sit at the top of the price range, focusing lenses in the middle, and collimating lenses near the focusing-lens range depending on diameter and LDT.
