The MT3A translation stage is offered with three differential micrometers for applications requiring increased resolution. The coarse adjustment, which can be locked using a thumbscrew on the mounting collar, provides 0.5 mm of translation per revolution over a range of 0.50" (12.7 mm). The quick-change modular design utilizes precision-aligned dowel pins to ensure orthogonality between stages and allows the user to reconfigure stages quickly as applications change.

Four 1/4"-20 (M6) counterbored slots on the included adapter allow the stage to be directly attached to a breadboard with user-supplied cap screws. Each stage contains seven 1/4"-20 (M6) and four 8-32 (M4) tapped mounting holes that are 0.22" (5.6 mm) deep.

The MT Series translation stages with differential adjusters can be purchased individually (MT1A Series) or as fully assembled, 3-axis, XYZ translators (MT3A Series). Therefore, the MT3A stage can be disassembled using a 3/16" (5 mm) hex key to customize the positions of the micrometers or to use three MT1A stages separately. See the XYZ Assemblytab for details.
