For applications that require increased resolution, the MT1A(/M) translation stage is configured with the  differential adjuster. The differential adjustment knob provides 25 µm of translation per revolution over a 250 µm range and is engraved with graduations every 0.5 µm. The coarse adjustment, which can be locked using a thumbscrew on the mounting collar, provides 0.02" (0.50 mm) of translation per revolution over a range of 0.50" (12.7 mm). Each stage contains seven 1/4"-20 (M6) tapped mounting holes which are 0.25" (6.2 mm) deep.

Two oversized 1/4"-20 (M6) counterbores allow the stage to be directly attached to a mounting adapter (sold below) or a metric or imperial breadboard with user-supplied cap screws.

The bottom face of the MT1A(/M) has four 8-32 (M4) tapped holes for mounting which are exposed when multiple stages are used to form a 2- or 3-axis stage. See the XYZ Assembly tab for more information.

The MT405 Side-Mounted Actuator Adapter (sold below) is designed to mount the adjuster only on the side without the plate. The side of the stage with the locking plate is not designed to mount an adjuster. See the Actuator Removal tab, above, for details about side-mounting the adjuster on an MT1A(/M) stage.
