Motorized stages are ideal for remote or automated positioning of optical components or subassemblies. In addition to all the precision features of their manual counterparts, the motorized actuator provides speed and resolution that cannot be achieved by manual adjustment. Three types of linear stages are available: a 65X65-mm aluminum ball bearing stage designed for general use, a 65X65-mm stainless steel crossed-roller-bearing stage designed for precision applications, and a 120X120-mm aluminum crossed-roller-bearing stage designed for larger loads and extended travel. Melles Griot motorized rotation stages provide precise, automated rotation for optical components and subassemblies. These stages combine the advantages of quick manual positioning with high-resolution stepper-motor adjustment. Use the manual positioning feature for proper orientation and, with the twist of a thumbscrew, engage the stepper motor for exact automated alignment. Vertical stages provide motorized translation in a direction perpendicular to their mounting surfaces. The smooth vertical travel is guided by three rows of precision crossed-roller bearings and is driven by a cam mechanism which converts the horizontal motion of the motorized actuator to a vertical stage motion. The nonrotating spindle on the actuator improves performance by reducing contact friction. Available in inch or metric versions, these stages can be easily combined with the linear translation stages to create x-y-z configurations.
