The CO₂ Laser Focus Lens PVD ZnSe Ø20 mm, FL 101.6 mm is a high-precision optical component designed to deliver clean focus, stable beam transmission, and consistent cutting or engraving quality in CO₂ laser systems.
Manufactured from high-purity Zinc Selenide (ZnSe) and coated with an advanced PVD (Physical Vapor Deposition) layer, this lens offers excellent infrared transmission, superior thermal stability, and enhanced resistance to heat and contamination. The 101.6 mm focal length (4”) provides an optimal balance between cutting depth and engraving detail, making it suitable for a wide range of materials and applications.
Ideal for professional and industrial laser machines, this focus lens ensures high energy efficiency, minimal beam loss, and long service life, even under continuous operatio
