Features
![]() Click to Enlarge DT12 Stages are Post Mountable via a Bottom-Located 8-32 (M4) Mounting Tap These Dovetail Translation Stages are compact, entry-level positioners, ideal for use in applications where space is limited. Each stage has a 1.00" x 1.00" (25.4 mm x 25.4 mm) platform that can be translated up to 1/2" (12.7 mm) using a precision M3 x 0.35 adjuster. The moving platform can be locked using a side-located setscrew and 0.05" hex key. An 8-32 (M4) tap on the bottom of the stage allows it to be mounted on Ø1/2" posts, while a top-located Four stage configurations are available: single-axis, XY, XZ, and XYZ. In order to guarantee orthogonality of the axes, XY configurations must be ordered preconfigured from Thorlabs. Pre-configured multi-axis stages also include a base plate for mounting the stages to an optical table.
Accessories
Manual Linear Translation StagesThorlabs' manual translation stages are offered in a range of maximum travel distances, from less than 1/4" (6 mm) to 2" (50 mm) and longer for our long travel, large area platforms. Many of these stages can be ordered in multi-axis configurations, providing XY or XYZ translation. For fiber coupling applications, please see our Multi-Axis Stages, which offer finer adjustment than our standard manual translation stages. In addition to linear translation stages, we offer rotation stages, pitch and yaw platforms, and goniometers. We also offer motorized translation stages that are powered by DC Servo motors, stepper motors, or direct drive technology. Crossed-Roller Bearing StagesThese linear translation stages feature crossed roller bearings travel mechanisms for precision motion, high load capacity, and low angular deviation. The LNR Series stages feature all-steel body construction, while the LX, XRN, and XR Series stage bodies are constructed of aluminum.
Ball Bearing StagesThese translation stages feature hardened steel linear bearings for precise motion and long life. They are available with a variety of actuators and in single-axis or preassembled multi-axis configurations.
Dovetail StagesThese compact stages incorporate dovetails and a leadscrew for the translation mechanism. They are suitable in general purpose motion control applications.
Flexure StagesThorlabs' Nanoflex™ translation stages feature frictionless flexure mechanisms for improved positioning and resolution when compared to similar stages made using bearings. The translation of the stage is accomplished by the elastic deformation (flexing) of a linkage attached to the mounting platform. Most models also include piezo actuators for small position adjustments.
Vertical StagesWe offer vertical translation stages with crossed roller bearings for precise motion as well as long travel vertical stages for heavy-duty applications.

Each stage also includes a base plate to mount it directly to an optical table. Please note that XY configurations must be ordered preconfigured from Thorlabs in order to guarantee orthogonality of the axes. The stages are permanently attached and cannot be separated. Preconfigured 3-axis stages are available below. ![]() ![]() Click to Enlarge DT12A Angle Bracket Replaced with the DT12RA Rotation Adapter (Available Below)
The DT12XYZ(/M) is a compact, three-axis translation stage that incorporates a dovetail and lead screw translation mechanism for smooth linear positioning along the entire range of travel for each axis. It consists of a DT12XY(/M) 2-Axis Stage with a DT12(/M) stage attached using a DT12A Angle Bracket. The stage also includes a base plate to mount it directly to optical tables. Please note that the two stages forming the XY portion are permanently attached and cannot be separated. ![]() ![]() Click to Enlarge A DT12 Stage with a DT12CTA Top Plate and CT101 Optic Mount ![]() Click to Enlarge A DT12 Stage with a DT12CTA Top Plate and CT104 Rotation Mount
The DT12CTA(/M) Top Plate features an array of tapped mounting holes with two 4 mm wide keyways to provide increased mounting options for our line of DT12 Dovetail Translation Stages. Two orthogonal keyways facilitate the mounting of CT1 stage accessories, such as translation and rotation mounts for Ø1/2" optics or SM1-threaded (1.035"-40) mounts, as shown in the images to the right. When mounted, the optical axis will be 38.5 mm (1.51") from the base of the translation stage. The plate also contains twelve 4-40 (M3) and four 8-32 (M4) tapped mounting holes for securing and mounting various components. For complete dimensions and mounting hole locations, please see the mechanical drawings in the table to the right. The top plate is attached to the DT12 dovetail stage via a central #8 (M4) counterbore and included 8-32 (M4) button-head screw. A lip that runs along a bottom edge of the plate creates a reference edge that prevents unwanted rotation of the plate when it is attached to the stage. ![]() ![]() Click to Enlarge A DT12A Angle Bracket shown mounting two DT12 Stages perpendicular to one another.
