20mm 25mm Beam Combiner ZnSe CO2 Laser Beam Combiner

  • ZnSe Laser Beam Combiner
  • CO2 Laser Beam Combiner 20mm 25mm
  • CO2 Laser Optical Components

  • CO₂ laser beam combiner is a precision ZnSe optical element designed to merge two or more infrared laser beams into a single coaxial output path. 

    With transmission exceeding 99% at 10.6µm and a low-reflection AR coating optimized for the 9–11µm band, the combiner minimizes insertion loss while maintaining beam quality (M²) on the combined axis. 

    Available in standard 20mm and 25mm diameters, it mounts directly into existing 1-inch or 30mm lens tubes and optomechanical holders without adapter hardware.
