Scanning laser systems—whether for marking, engraving, or for drilling micro via holes—all rely on galvo mirrors to precisely position the laser beam. II-VI manufactures built-to-spec galvo mirrors from mirror-grade silicon substrates. We apply our precision thin-film coatings to these substrates, producing highly efficient galvo mirrors that reflect laser light in the 1.0 to 12.0 µm range.
Ideally suited for Nd:YAG lasers (1.06µm) and CO2 lasers (9.3 to 10.6 µm), II-VI galvo mirrors are suitable for a wide range of industrial applications. And for those applications requiring a visible helium-neon or diode laser alignment beam, our dual wavelength coatings provide maximum reflectivity for the CO2 laser infrared beam while providing good reflectivity for the visible alignment beam. Our Dual Enhanced Maximum Metal Reflection (DEMMR) coating is the best choice for this application. (Details are shown in Figures 1 and 2.)
II-VI galvo mirror sizes typically range from 0.5 to 4.0 inches in diameter, based on OEM specifications.
