Frequently Asked Questions

Q: What is the difference between CVD ZnSe and regular ZnSe?
A: CVD (Chemical Vapor Deposition) ZnSe is produced using a high-purity manufacturing process that results in lower absorption, higher thermal conductivity and better optical homogeneity compared to regular ZnSe. This makes CVD ZnSe lenses more durable, more efficient and better suited for high-power CO2 laser applications.

Q: How do I choose the correct focal length?
A: Shorter focal lengths (38.1mm-50.8mm) provide a smaller spot size and higher power density, ideal for engraving and thin material cutting. Longer focal lengths (63.5mm-127mm) provide a deeper depth of field, better for cutting thicker materials. Always match the focal length to your original lens for best performance.

Q: How often should I replace the CO2 focus lens?
A: Under normal operating conditions, a CVD ZnSe focus lens should last 3-6 months. However, it should be replaced immediately if you notice any film burning, scratches, or if cutting/engraving quality deteriorates. Poor air filtration and frequent cutting of oily materials will accelerate lens contamination.

Q: How do I clean the CO2 focus lens correctly?
A: Always wear clean gloves when handling optical lenses. Use a blower ball first to remove loose dust. Then fold a lint-free microfiber cloth into a small square, apply a small amount of lens cleaning fluid, and gently wipe the lens surface in a single direction from the center to the edge. Never use regular paper towels or tissues.

Q: Can I use this lens for fiber laser machines?
A: No, this lens is specifically designed for 10.6μm CO2 lasers. It will not work for 1064nm fiber lasers. Using the wrong wavelength lens will result in extremely high absorption, causing the lens to overheat and crack almost immediately.
