Precise and smooth linear translation with no backlash is achievable by dovetail guides and a spring-loaded micrometer or lead screw mechanism. The springs pre-load the moving plate, elimination an backlash. In the tables below x stands for 1–axis stage and x-y stands for a combination of 2-axis stage. A denotes micrometer drive; B denotes side-mounted drive. With product GCM-53 series, one can build a 3-axis translation stage.
GCM-122101M XY Translation Stage manufactured by Daheng Optics utilizes ground dove-tail guide rails as the guiding mechanism and precision thread pairs as the driving components. With a table size of 65x65mm, a stroke of ±3mm, and a thin, compact structure, it features four φ7mm through-holes with a 50mm hole pitch at the bottom for direct connection to optical platforms. M4 threaded holes on both sides allow for mounting with support rods.
