CO₂ Laser Beam Expander

Beam expanders developed for CO laser are made by ZnSe material which has the highest transmission for CO laser. We provide a wide range of magnifications from 1x to 20x. With dedicated mechanical structure, the internal lenses don’t rotate during adjustment, which ensures the best alignment accuracy. Adjustable ring with scales makes it more convenient for user’s operation. UniBET series beam expanders are developed for higher power (>100w) CO2 laser without water cool. It has consistent outer dimension and connecting thread M30x1. A laser beam expander is designed to increase the diameter of a collimated output beam. It is used in applications such as laser scanning, interferometer and remote sensing. BET-WC Series water cool beam expanders are developed for even higher power (>200W) CO lasers with consistence in outer dimension and water pipe connection. MiniBET series have the same external diameter of 20mm, thread M16x0.75 and it is widely applied in compact CO laser system.

製品説明

CO₂ Laser Beam Expander

Eternal Optics manufactures precision CO₂ Laser Beam Expanders designed for advanced 10.6 μm CO₂ laser systems, providing accurate beam expansion, divergence reduction, and improved laser beam delivery performance for industrial laser applications.

A CO₂ Laser Beam Expander is an optical assembly used to increase the diameter of a laser beam while reducing its divergence angle. By optimizing beam size and propagation characteristics, beam expanders improve focusing performance, extend working distance, and enhance the overall efficiency of CO₂ laser processing systems.

Our 10.6µm Beam Expanders are manufactured using high-quality infrared optical materials, including ZnSe (Zinc Selenide), with wavelength-specific AR (Anti-Reflective) coatings designed for CO₂ laser applications. These optics provide high transmission, low absorption, excellent thermal stability, and reliable performance under high-power laser operation.
