Any of the translation stages featured here can be purchased as a special order without an actuator, thereby allowing the user to choose from our large selection of manual and motorized actuators. We also offer screw adjusters that have Ø3/8" barrel adapters for 1/4"-80, 1/4"-100, or M6 x 0.25 threads, making them compatible with the stages below. When choosing a custom actuator, please be aware of the barrel size of the actuator. Please contact Tech Support to discuss the various micrometer options and to get quotes for custom configurations with or without alternative actuator options.

Another solution is to purchase the Mitutoyo® 05CZA662 SPC cable and IT-016U USB input tool that provide a push button and USB interfacing cable. With this device the user can open any text entry software package, press the single push button, and the device acts like a keyboard to enter the number into the software.

The PT3A(/M) translation stage is offered with 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 1" (25.4 mm).

These linear translation stages feature crossed-roller bearing 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 cast tool and jig aluminum. We also offer several vertical crossed-roller bearing stages (see below).

Digital micrometers, such as the DM713, are handy for moving a piece of optomech a specific distance. For example, a user might want to increment a translation stage holding a sample in front of an objective lens in order to focus the light to equally spaced points within the sample.

Thorlabs' 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.

Using the DM713 alone creates an extra step where the user has to read and record the display, which can be tedious in a dark lab where the display is not visible. One solution is to use Thorlabs' SBC-COMM, which includes an RS-232 interfacing cable. Thorlabs has created software application notes that walk the user through creating Visual C#® and LabVIEW® programs to continuously measure distances with the DM713. The application notes can be downloaded from links in the following section.
