Thorlabs' PT Translation Stages have a 1.00" (25.0 mm) translation range and feature hardened steel linear bearings for precise motion and long life. These translation stages are available preconfigured with an adjuster screw, standard manual micrometer, or differential adjuster. The actuator on the translation stage can be removed by loosening the screw on the barrel clamp with a 3/32" (2.5 mm) hex key.
Each stage comes with two precision dowel pins that allow the PT series of translation stages to be stacked in right- or left-handed XY configurations with excellent orthogonality of <5 mrad. The right-handed XYZ configuration, with either the standard manual micrometer or the differential micrometer, is available fully assembled below.
Custom Options
Any PT series translation stage can be purchased as a special order without a micrometer, 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. Please see the selection guide in the Actuators tab for a list of compatible actuators. Please contact Tech Support to discuss the various micrometer options and to get quotes for custom configurations with or without alternative actuator options.
PT101(/M) Base Plate
The PT101(/M) Base Plate is ideal for XY or XYZ multi-axis configurations where the standard counterbores in the middle of the stages are obstructed. It has 1/4" (M6) counterbore slots for mounting to a breadboard or optical table and comes with the two 1/4"-20 (M6) cap screws that are needed to attach it to a PT series stage.
PT102(/M) Angle Bracket
The PT102(/M) Angle Bracket allows for a PT series stage to be oriented vertically, making left- or right-handed XYZ, XZ, and XY configurations possible. For information on constructing an XYZ configuration from individual components, see the XYZ Assembly tab.

XYZ Assembly
The modular design of the PT series translation stages allows the assembly of 2- or 3-axis stages within minutes. Each stage comes with two precision dowel pins that allow for right- or left-handed XY configurations with excellent orthogonality. Follow the steps in the animation to the left or the photos below to build a 3-axis XYZ translator (PT3) from individual components.
Step One
![Step 1](https://www.thorlabs.us/images/TabImages/Linear_Translation_Stage_PT1_A5-375.jpg)
Insert the two 1/8" alignment pins into the PT101(/M) Base and then screw it onto a PT series translation stage using the two included 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes to ensure orthogonality of the second stage.
Step Two
![Step 2](https://www.thorlabs.us/images/TabImages/XY_Translation_Stage_PT1_A5-375.jpg)
Attach the second, orthogonal PT series translation stage, as shown above, using two 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes for aligning the angle bracket.
Step Three
![Step 3](https://www.thorlabs.us/images/TabImages/XY_Translation_Stage_PT1_PT102_A5-375.jpg)
Screw the PT102(/M) Angle Bracket to the PT series translation stage, as shown above, using two 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes on the front face of the angle brakcet for aligning the third and final stage.
Step Four

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.
However, there are also times where the user might want to record the position of an event. One example could be making a distance measurement where the micrometer is set to a starting position, zeroed, and then translated the desired amount to display the distance.
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.
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.

 (posted 2024-07-17 16:23:27.647) I have got the confusion with the PT3/M's frontside, bolt and dowel pin attaching insert section.
I am preparing a counter parts for this PT3/M stage module.
At the front side,
much of M6 thread holes and 2 of dowel pin attaching positions are exist.
And among the repeating of the bolt and dowel pin insert holes,
instead of normal undertstanding (commonly it would be understood as the distance between is 12.5mm, as the PDF format part drawing description)
but there have some of measured part as 12.49mm in the 3D modeling STP data,
Can you tell me which of exact distance value is correct?
Actually, 0.01mm deviation, can be easily passed over,
but considering the tolerance stack of the counter part's attaching positional vary, I think it should be exactly kept.
Thank you and best regard.
if there needs any reference image or any data please let me know
i will feedback through the mail. (sjkim@korthern.co.kr) jdelia
 (posted 2024-07-18 09:07:04.0) Thank you for contacting Thorlabs. The spacing you are referencing has a nominal value of 0.492" (12.4968 mm). Stuart MacFarquhar
 (posted 2023-03-15 16:04:49.877) Please could you review the AutoCAD PDF technical drawing, specifically the spacing of the tapped M6 holes? These are listed as separated by 25.4 mm, however a custom part ordered to fit these does not fit, and measurement of the PT1/M plate suggests the spacings are in fact 25.0 mm. jdelia
 (posted 2023-03-24 10:01:04.0) Thank you for contacting Thorlabs. The M6 tapped holes on the PT1/M are in fact spaced 25 mm apart. The 25.4 mm measurement you mentioned just refers to the two center counterbored holes. I have reached out to you directly to clarify this further. Philipp Treutlein
 (posted 2023-02-21 14:08:29.243) Can I order the 1/8 alignment pins separately? jdelia
 (posted 2023-02-22 10:09:19.0) Thank you for contacting Thorlabs. We are reaching out to you directly regarding a quote for these component dowel pins. tom.dzelzainis
 (posted 2019-03-12 10:53:27.517) Hi,
Is it possible to get the PT3 with imperial tapped holes, but a metric micrometer.
Thanks,
Tom. llamb
 (posted 2019-03-12 03:41:47.0) Yes. You may manually swap the 150-801ME metric micrometers into the PT3 after removing the imperial 150-811ST micrometers. Otherwise, you may contact techsupport@thorlabs.com for requests on custom pre-configured products. We have reached out to you by email to quote this particular custom product. mark_bowen
 (posted 2017-12-12 17:03:32.893) We have used hundreds of PT1 stages in the past. They proved to lack sufficient stiffness for my recent application, so I considered the DTS25 as an option. The website provides stiffness specs for the DTS, but the specs for the ball and roller slides do not. That would be a helpful characteristic to list so the products can be compared. tfrisch
 (posted 2017-12-15 09:51:06.0) Hello, thank you for contacting Thorlabs. PT1 has its micrometer attached to the moving carriage rather than the baseplate, so likely the effect you are seeing is due to the weight or torque of your hand moving the stage. I will pass on your note about product comparison characteristics to our Engineering Team. clare.dillon
 (posted 2016-07-25 09:55:33.307) I wondered if you could tell me what the repeatability of the PT1/M micrometer is please, and what the hysteresis is in the mechanism? Thanks. cpepe
 (posted 2016-06-07 15:11:55.133) Hi, I was wondering if you could tell what material the "XYZ Translation Stage with Standard Micrometers PT3/M" is made of? besembeson
 (posted 2016-06-08 09:42:26.0) Response from Bweh at Thorlabs USA: It is mostly anodized aluminum (for the main body) and hardened alloy and stainless steel for other sub components. tomerg
 (posted 2015-11-04 09:03:15.663) Hello, I want to inquire regarding the PT1A/M: the distance between the CBORE for M6 is 25.4mm while for most of the metric products the mounting holes distance is 25mm. Is it Ok? is there enough freedom to assemble the PT1A/M on metric items (specifically, AP30/M)?
Thanks, Tomer. jlow
 (posted 2015-11-04 11:57:47.0) Response from Jeremy at Thorlabs: The counterbored holes on the metric PT1-series stages are oversized so they can be used on 25mm hole pattern. t.isaac
 (posted 2015-05-05 10:51:24.09) Please could you tell me the maximum cantilevered load (axial and transverse) of the PT1A/M stage? cdaly
 (posted 2015-05-18 08:50:40.0) Response from Chris at Thorlabs: At the moment, we do not have measured limits for the permissible torque on the PT1 series of stages, but we will contact you directly in order to discuss your application and how appropriate this stage if for you. khaded
 (posted 2014-12-05 10:31:14.7) How can I order the PT3 stage with the bottom stage rotated 180 deg. (because of interference of the micrometer with another component).
Thanks,

 (posted 2011-01-26 14:10:20.0) We have tested the PT1/M in a similar setup by mounting a P4 (4” long post), a PT3 and then two MB12s (6kg total) onto the P4 post. In this arrangement, the vertical stage still moves smoothly so you should not experience any degradation in performance. Please contact TechSupport@thorlabs.com if you want to further discuss your application. remco.de.vries

 (posted 2007-11-13 05:20:31.0) if I click on PT3 a picture is shown that includes a block between the second and third stage. This block would be very helpful. Which item number is it? acable
 (posted 2007-08-20 13:25:06.0) It would also be nice to use the same sort on the price box for the metric products as is used for the imperial products. Also even if the PT101 is truely universal i would list it in both price boxes, it is arkward to need to go into two places to put together a system. europe
 (posted 2007-08-20 10:43:38.0) please take a look on the web page for PT101 :
there is no hint for customers that the PT101 is universal ( if so why does it have 1/4-20 tap???) and fits with the /M parts - can you advice with the web team that they do a comment?

Manual Linear Translation Stages
Thorlabs' 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 Stages
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).

Flexure Stages
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.

PT101 Base Plate used to create clearance for mounting a DM713 Digital Micrometer to a PT1 Stage.
- Build XY and XYZ Configured Stages
- Base Plate for Optical Breadboard Mounting
- Angle Bracket for Vertical Mounting
The PT101(/M) and PT102(/M) are adapter plates designed for the PT Series translation stages. The PT101(/M) has four 1/4"-20 (M6) mounting slots on the side that enable obstruction-free mounting onto an optical breadboard. It is ideal for XY configurations or already assembled XYZ multi-axis configurations where the standard counterbores in the middle of the stages are obstructed. This base plate includes two alignment dowel pins and two 1/4"-20 (M6) cap screws.
The PT102(/M) is an angle bracket with four 1/4"-20 (M6) mounting holes that allows a PT Series stage to be mounted vertically. This is necessary in all XZ and XYZ configurations. The adapter plate includes four 1/4"-20 (M6) cap screws. It is also compatible with our manual and motorized MT Series translation stages that offer 1/2" (12.7 mm) of travel. This allows stages with different travel ranges to be easily connected within the same mechanical system.
The PT3(/M) XYZ configured stages include both the PT101(/M) and PT102(/M) adapters. Please see the XYZ Assembly tab for more information on using these adapters to create a multi-axis configuration.
