  • 1. 【Standard 101.6mm (4.0") Focus for Sharp Engraving & Clean Cutting】 Precisely engineered with a 101.6mm (4-inch) focal length, this lens delivers the ideal balance between detail resolution and cutting depth. It produces crisp engraving on wood, leather, and glass, while ensuring smooth, polished edges when cutting acrylic and plywood up to 15mm thick – making it the most versatile choice for diverse projects.
  • 2. 【CVD ZnSe with AR Coating, High Power 200W Support】 Crafted from premium CVD ZnSe (Chemical Vapor Deposited Zinc Selenide) with dual-sided AR coating, this lens handles demanding applications up to 200W. The superior material and coating ensure >99.5% transmittance at 10.6µm, maximizing energy delivery for faster processing and reduced laser tube strain.
  • 3. 【Meniscus Design for Superior Beam Convergence】 The meniscus (curved) optical design is optimized for the 10.6µm CO2 laser wavelength. It minimizes spherical aberration and beam divergence, creating a tighter, more consistent focal point than flat lenses. This results in higher precision cuts and more detailed engravings across your entire workspace.
  • 4. 【Direct Replacement for K40, OMTech, Universal & More】 With a standard 20mm diameter, this lens is a direct drop-in upgrade for most CO2 laser systems. It seamlessly replaces original lenses in K40, OMTech, Universal Laser Systems, Boss, Trotec, and similar 30W-200W machines, restoring peak performance with a simple 5-minute installation.
  • 5. 【Protected Delivery & Performance Ready】 Each lens is precision-cleaned and housed in a static-safe, foam-lined storage case to prevent scratches. It arrives ready to transform your laser’s output—no special tools or adjustments needed. Experience professional-grade optics that bring out the best in your machine.
