- Superior Meniscus Design: Unlike standard plano-convex lenses, the meniscus shape (curved on both sides) is specifically designed to minimize spherical aberration. This creates a significantly smaller and sharper focal spot, which is essential for achieving cleaner edges and finer details in both cutting and engraving.
- High Transmittance: Featuring a high-grade double-sided anti-reflective (AR) coating, this lens achieves a laser transmittance rate of ?99.8%. This minimizes power loss and prevents the lens from overheating during high-power operations.
- Extreme Durability: The CVD ZnSe substrate is highly resistant to thermal shock and can handle power levels from 40W up to 200W+ (with some variants rated up to 300W). Its tough coating also offers excellent scratch and wipe resistance for a longer service life.
