CO₂ Laser ZnSe Focus Lens 25.4mm x 3mm ET for 10.6µm Systems - AR (Anti-Reflective Coating)

Overview The ZnSe Meniscus Focus Lens is a precision optical component designed to focus CO₂ laser beams for engraving, cutting, marking, and material processing applications. Manufactured from premium laser-grade zinc selenide (ZnSe) in the USA, this lens is optimized for 10.6µm CO₂ laser systems and delivers consistent beam focusing performance while maintaining excellent optical transmission characteristics. With a 25.4mm (1.0") diameter, 101.6mm (4.0") focal length, and 3mm edge thickness, this lens is suitable for a wide range of laser cutting and engraving systems operating at power levels up to 500W. Technical Benefits The premium ZnSe substrate provides high transmission at CO₂ laser wavelengths, helping maximize delivered laser energy while minimizing optical losses. The anti-reflective coating further improves transmission efficiency and supports consistent beam quality. The meniscus lens design promotes effective beam focusing for clean cutting edges and detailed engraving results. Excellent thermal stability helps maintain optical performance during extended operation in industrial environments. Manufactured to tight dimensional and focal length tolerances, this lens provides reliable integration and repeatable processing results across a variety of laser applications. Applications CO₂ laser cutting systems Laser engraving equipment Industrial material processing Sign and graphics production Wood engraving and cutting Acrylic and plastics processing Leather engraving OEM laser system integration Manufacturing and fabrication environments Integration Notes This lens is designed for use with 10.6µm CO₂ laser systems and should be installed according to the laser machine manufacturer's optical configuration requirements. Verify lens diameter, focal length, and mounting compatibility before installation. Proper lens handling and cleaning practices are recommended to maintain optical performance and service life.
