CO2 Laser Lens for Engraving Cutting 40W-200W

The CVD ZnSe Laser Lens is a high-quality optical component featuring exceptional performance characteristics. Crafted from premium-grade CVD (Chemical Vapor Deposition) ZnSe material sourced from the United States, this lens offers unparalleled stability and power density endurance, making it compatible with laser systems ranging from 40W to 200W.

Boasting a diameter of 20mm (0.79") and a focal length of 63.5mm (2.5"), the lens maintains a thickness of 2.0-2.2mm (0.08") while delivering an outstanding transmittance of ≥99.8%. This remarkable optical efficiency is achieved through a meticulously engineered double-sided solid coating, which not only increases the lens's service life but also reduces laser loss, enhances wiping resistance, and provides exceptional high-temperature resilience.

The exquisite manufacturing process, including precision slicing, polishing, and grinding, ensures the CVD ZnSe Laser Lens delivers excellent optical properties and high working efficiency. The smaller focusing spot size and more concentrated energy output make this lens an ideal choice for CO2 laser engraving and cutting applications, where increased productivity and precision are paramount.

Regarding the lens shape, the CVD ZnSe Laser Lens typically features a plano-convex design, although some meniscus shapes may be encountered during manufacturing, with the same effective performance as the plano-convex configuration.

Attention should be paid to several factors to ensure the longevity and proper operation of the lens. Firstly, adequate air cooling is essential to prevent overheating and potential cracking of the lens. Secondly, the presence of condensation water droplets within the lens barrel can also lead to lens breakage and should be avoided. Thirdly, the accumulation of cut or engraved material on the lens surface can result in uneven heating, potentially causing the lens to break, necessitating regular cleaning with cotton balls dampened in absolute alcohol or acetone.

Finally, when adjusting the light path, care must be taken to ensure the laser beam does not accidentally strike the edge of the lens or the junction of the lens barrel, as this can also result in lens breakage.

In summary, the CVD ZnSe Laser Lens is a high-performance optical component designed for demanding CO2 laser engraving and cutting applications. Its exceptional material quality, precision engineering, and attention to detail make it a reliable and efficient choice for users seeking to maximize the productivity and performance of their laser systems.
