How to Select a CO2 Laser Beam Combiner
Selecting the right CO2 laser beam combiner depends on the laser wavelength, visible aiming wavelength, beam diameter, laser power, angle of incidence, and coating requirements. For most industrial CO2 laser systems, the primary wavelength is 10.6 µm, while a visible red alignment beam may also need to pass through or reflect from the same optic.
When requesting a quotation, please provide the CO2 laser wavelength, visible aiming wavelength, optic diameter and thickness, laser power, angle of incidence, and required transmission or reflection performance. Clarvis Industrial can support custom ZnSe beam combiners with application-specific coatings, dimensions, and OEM specifications.
Product Overview
Accurate Visible Positioning
Specifically designed to combine invisible CO2 laser beams with visible diode laser pointers. This allows for precise workpiece positioning and path simulation, significantly reducing setup time and material waste in high-speed laser processing.
Advanced Optical Coating
Utilizing state-of-the-art vacuum deposition technology, our combiners feature high-damage threshold coatings. This ensures maximum transmittance at 10.6μm and peak reflectance for red light, maintaining beam integrity even in 500W+ systems.
Rigorous Alignment Validation
Every Clarvis Industrial beam combiner undergoes comprehensive interferometric and spectral testing. We guarantee minimal wedge error and surface distortion, ensuring your laser head consistently delivers the combined beam to the exact target point.
