Features

Modular Design Allows Stages to be Easily Configured in XY and XYZ Orientations
Micrometer- or Differential-Actuator-Equipped Models Available
Wide Range of Compatible Actuators (See Actuators Tab for Details)
1/4"-20 (M6) Mounting Holes

The PT series of translation stages have a 1" (25 mm) translation range and feature hardened steel linear bearings for precision motion and long life. These translation stages are available preconfigured (see note below) with a standard manual micrometer or a differential micrometer. The actuator on the translation stage can be removed by loosening the screw on the barrel clamp.

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. The right-handed XYZ configuration is available fully assembled as the PT3 (PT3/M) and PT3A (PT3A/M) below.

Note: 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. Please see the selection guide in the Actuators tab for a complete list of compatible actuators.

PT101
The PT101 Base Plate can be used with either an imperial or metric stage. It comes with the two 1/4"-20 cap screws that are needed to attach it to an imperial or metric PT series stage.

PT102
The PT102 Angle Bracket allows for a PT series stage to be oriented vertically, making left- or right-handed XYZ, XZ, and XY configurations possible.

PT1 with DM713 Digimatic Micrometer

Any of the translation stages featured here 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. When choosing a custom actuator, please be cognizant of the barrel size of the actuator. The selection guide below provides a complete list of compatible adjusters for the PT series of translation stages.

Our technical support staff is also available to discuss the various micrometer options with you and provide quotes for custom configurations with or without alternative actuator options.

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 below to build a 3-axis XYZ translator (PT3) from individual components.

Step One

Screw PT101 Base to PT1 Translation Stage using two 1/4"-20 cap screws.

Step Two

Attach second, orthogonal PT1 Translation Stage, as shown above, using two 1/4"-20 cap screws.

Step Three

Screw PT102 Angle Bracket to PT1 Translation Stage, as shown above, using two 1/4"-20 cap screws.

Step Four

Screw third PT1 Translation Stage to back of PT102 Angle Bracket, using two 1/4"-20 cap screws.

Response from Tim at Thorlabs: To avoid obstructing the path during translation underneath the mounting body, the screws should not exceed the length of the tap, which is just over 5.8mm.

What's the maximum lnegth of 1/4-20 screws that can be used with the PT1?

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.

Dear sir, I want to use the PT1/M for a construction. Therfore we have to munt a approc. 6kg heavy chamber a 10 cm of the stage. The stage itself can bear 9kg, but Im interesting in the pitch moment of the stage. Is this possible with this stage? with kind regards, Remco de Vries

Is the PT102 cmapatible with the dovetail translation stages like DT25?

Poster: Thorlabs

Posted Date: 2010-06-29 11:01:34.0

Response from Javier at Thorlabs to martin.kahle: The PT102 is not compatible with the DT25 stages; the mounting holes do not match. However, the AP90 right angle bracket is compatible with these dovetail stages (http://www.thorlabs.de/NewGroupPage9.cfm?ObjectGroup_ID=224&pn=AP90). I will send you an assembly example consiting of two DT25 stages and one AP90.

Response from Javier at Thorlabs to last poster: you do not need to buy additional components in order to complete the assembly of the PT3A/M. The actuators, right angle bracket, and mounting base are all included.

Dear Sir Do I need any other accessories like actuators, base plates for PT3A/M

Response from Javier at Thorlabs to michael.roth: The PT101 is compatible with both imperial and metric versions of the PT1. The slotted mounting holes provide enough clearance so that you can attach the base onto a breadboard/optical table with 50.0 mm hole spacing.

Hello, i need to mount a PT1/M Translation Stage on a breadboard with 50.0mm hole spacing. What would you recommend since the PT101 has a 51mm hole spacing? Can you use the PT101 also with 50mm hole spacings? Thank you for your answer.

A response from Adam at Thorlabs to Bowen: The distance from the bottom of the stage shown in detail A to the table top is 35.67mm when the stage is midway in travel. I will email you directly to see if any more dimensiosn are needed.

For the drawing of PT3, what users would like to know is the height of detail A above the tabletop (where the stage would rest). This value does not seem to be in the drawing. Youd really like to know it when the micrometer is in the midrange, not at one end of the travel.

Dear jschumacher, Thank you for brining our attention to the PT3 image. The picture was not accurate and has been replaced. The block is not part of the PT3 (Please see the updated image).

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?

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.

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? Thanks
