Beam Combiner Lens - Replacement Lens

Beam Combiner Lens is a high‑precision optical component designed to merge or direct laser beams within CO₂ laser systems and other infrared laser applications. Available in 20 mm or 25 mm diameter options, this beam combiner lens is made from high‑quality zinc selenide (ZnSe), a material known for its excellent transmission in the CO₂ laser wavelength range and superior performance under high‑power conditions.

Crafted to tight optical tolerances, the ZnSe Beam Combiner Lens ensures minimal loss and distortion of the laser beam, helping maintain consistent power delivery and optimal focus. It is commonly used in laser systems that require precise beam alignment, splitting, or combining functions—such as multi‑head laser cutters, advanced engraving machines, and custom laser configurations. The choice between 20 mm or 25 mm diameters allows compatibility with a wide range of optical assemblies and machine designs.

The durable ZnSe material supports excellent thermal stability and a high damage threshold, making the lens suitable for demanding industrial use. Whether you’re building a custom laser setup, upgrading existing optics, or replacing worn components, the Beam Combiner Lens provides reliable optical performance.

Easy to install and compatible with standard laser mounts, the lens is an essential part for achieving precise, stable beam control in CO₂ laser cutting and engraving applications.
