Details:Advantages

• Adopted ZnSe material imported from USA which can go with high power density;Deliang system, and increased the light transmittance of the parts;
• The transmittance of working waveband in
 co2 laser industry reaches 99.8%;
• The lens consist in many advantages such as precise focus, thin-film coating anti wiping, higher luminous flux, etc. For which materially improves your work efficiency.

Benefits
• Stable focus spot, better effect in cutting and engraving, bearable for high power density, and strong thin - film coating against peeling off and durable for wiping;
• Double-side coated anti-reflection coating, the light transmission of the parts increased by cylindrical surface polishing, reduction or elimination on stray light of the optical system;
• The stability of focus position strengthened, the cutting & engraving speed of some applications improved, and the ability for reflected light enhanced;
• More bearable for wiping, longer life span as well as better process to radioactive coating.
