Frequently Asked Questions

Q: How can I verify that the lens is a genuine II-VI product?
A: All genuine II-VI lenses have three anti-counterfeiting features: 1) Laser marking of the II-VI logo and part number on the lens edge; 2) Original II-VI hard plastic case with printed label; 3) Original II-VI certificate of authenticity with unique serial number. You can also contact II-VI directly to verify the serial number.

Q: What is the difference between II-VI lenses and other CVD ZnSe lenses?
A: II-VI is the world's leading manufacturer of ZnSe optical materials. Their proprietary CVD process produces material with significantly lower absorption, higher thermal conductivity and better optical homogeneity than other CVD ZnSe. II-VI's proprietary AR coating also provides higher transmittance and better durability than standard coatings. These differences result in 10-15% higher cutting efficiency and 2-3 times longer service life under high power operation.

Q: When should I choose II-VI lenses over other grades?
A: Choose II-VI original lenses if you have a high power laser (>1500W), require maximum cutting efficiency and quality, operate 24/7 in production environments, or want the longest possible service life. For low to medium power applications or budget-conscious operations, we also offer economical PVD and standard import grade CVD lenses.

Q: How long does an II-VI focus lens last?
A: Under normal operating conditions with proper maintenance, an II-VI focus lens should last 6-12 months. This is 2-3 times longer than standard CVD lenses. Service life can be extended by using proper air filtration, regular cleaning and avoiding cutting oily or reflective materials.

Q: Can I use II-VI lenses in any CO2 laser machine?
A: Yes, II-VI lenses are manufactured to standard dimensions and are compatible with all mainstream CO2 laser machine brands. They are a direct drop-in replacement for original lenses and require no additional debugging or modification.

Also available: Standard Import Grade CVD ZnSe Lenses and Economical PVD ZnSe Lenses for different budget and power requirements.
