2-Axis optical scan heads consists of X and Y galvo scanners, driver boards, XY mount, dust proof housing, F-theta lens adaptor, positioning plate for installation, 25-pin connector, and 3-pin power supply connector. Sophsticated designs secure that our 2-Axis optical scan heads perform at extremely high accuracy, low drift for a variety of different input apertures at various wavelengths. They are ideal solutions for applications that require high accuracy and extremely low drift. Typical applications include: additive manufacturing (3D printing), welding, scribing, marking, cutting, and micro structuring, etc.
