Most scan systems are equipped with suitable standard objectives or specialized optics. SCANLAB's optics experts provide a broad range of objectives tested for usability, coating choices and perfect compatibility. Our recommendations for suitable optics always take your specific requirements and applications into account. For some applications it is more advantageous not to use fixed lenses after the scanning mirrors to focus the laser beam. For such cases, SCANLAB offers dynamic z-axes that allow pre-focusing the laser beam.
Objectives are mounted at the scan system's beam exit. The focus optic's type and focal length (or back focal length) are optimized for your application's wavelength, laser power, spot size, image field size and working distance.
Scan systems can be equipped with a replaceable protective window to eliminate contamination risk during material processing.
F-Theta lenses enable ultra-accurate processing of flat image fields without dynamic limitations. A short-focal-length F-Theta lens facilitates short working distances, as well as very compactly-dimensioned systems. Long focal length, on the other hand, allows the processing of large image fields without external axes. SCANLAB offers a diverse variety of F-Theta lenses or flat field objectives (e.g. along with telecentric objectives). Customer-specific designs are possible, too.
