STN Series Scanning Galvanometer
STN scanning galvanometers are designed for precision laser drilling, cutting, and micromachining, with durability and performance proven in 24/7 production worldwide. Their flexibility supports complex geometries, taper angles, and shapes, producing circular, elliptical, square, and custom microholes. UV, green, and two infrared bands are supported, each with two focal-length choices. They work with most mainstream ultrashort-pulse lasers and monitor processing and beam characteristics during production. High power handling, easy setup and alignment, and preadjustment simplify subsystem setup and polarization calibration while minimizing downtime for continuous production. Specialized technology and resources provide customized solutions. Laser sources, scanners, and operating systems can be selected to develop processes for specific products, components, and materials. Process-control options: lens-vision module with built-in lighting; polarization control for optimal results; two beam-alignment cameras; automatic beam-position calibration; scanner-only supply; scanner with matched laser and beam path; fixed or movable base.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
