YEHE MACHINERY manufactures all kinds of laser lens for PRECITEC, RAYTOOLS, HANS, HSG,WSX,FRIENDESS,OSPRI,SUPLASER,QILIN,TRUMPF etc , ranges from protective , focus , alignment ,welding and engraving.
YEHE MACHINERY adopts imported premium quartz plate+imported lens grinding machines+imported metal hafnium film+imported film coating machines for manufacturing the high quality laser lens, YEHE lens not only protect your cutting/welding head,fiber cable, and laser source ,but also can realize long time cutting/welding and improve your cutting/welding quality.
YEHE MACHINERY takes rigorous inspection on each lens before shipment.
· High-quality Premium Quartz
· YEHE uses premium quartz for its protective lenses.
· Quartz has good thermal stability and is suitable for high-power fiber-laser applications.
· High light transmission
· YEHE lists transmission of >99.8% for one of its protective-window specifications.
· High transmission reduces optical loss and helps maintain stable cutting performance.
· High-quality AR coating
· YEHE adopts imported coating equipment and hafnium-based film/coating technology.
· A good AR coating reduces reflection and absorption, which is particularly important as laser power increases.
· Better resistance to thermal damage
· The protective lens sits directly in front of the cutting zone and is exposed to spatter, smoke and heat.
· Low absorption is important because excessive absorption can create a thermal-lens effect, causing focus drift and unstable cutting.
· Good optical precision
· Surface quality: 40-20 scratch-dig
· Clear aperture: ≥85%
· Flatness: up to λ/2 per inch @633 nm, depending on specification
· Diameter tolerance: ±0.1 mm
· Thickness tolerance: ±0.05 mm
