Do you often worry about power loss in your laser beam, the risk of lens damage, or thermal lensing effects that compromise system stability?
No need to worry! Our high-performance lenses are manufactured with advanced anti-reflection (AR) thin-film coating technology, which minimizes laser beam absorption and ensures highly efficient energy transmission. The AR coating features a dense structure close to that of bulk material, dramatically reducing light absorption. This results in a significant increase in transmittance, thereby enhancing beam delivery and ensuring stable and efficient operation of your laser system even under high-power output.
If your laser system requires enhanced reflection, we also offer high-reflection (HR) coating options specifically designed for applications that demand efficient light reflection. These lenses perform exceptionally well in high-power laser applications, providing reliable reflectivity and long-term stability under intense laser irradiation, effectively preventing damage or performance degradation caused by thermal effects.
Whatever your optical requirements may be, our lens series can meet them. We provide a wide range of focal lengths and radii of curvature, customizable to your specific application needs, ensuring optimal optical performance and outstanding laser system operation. Feel free to contact us to choose the most suitable lenses for your system and take your laser technology to the next level!
Disclaimer: The focal length or radius of curvature (ROC) values given in the product description are calculated reference values at the coating design wavelength and are provided for reference only.
Notes: To ensure the best performance, it is recommended to store and use the lenses at 25 °C with a relative humidity of 40%–60%. If the lens surface becomes contaminated, gently clean it using >99% alcohol and lint-free lens tissue. Do not use rough cloth, water, or cleaners containing abrasive particles, as this may damage the coating.
