1" (25 mm) Travel Translation Stages




  • 3"x4" Stage with 1/4"-20 Mounting Holes
  • Modular Design for 1-,2- or 3-Axis Stages
  • 90 lbs. Horizontal Load & 20 lbs. Vertical Load

Features

  • Modular Design Allows Stages to be Easily Configured in XY and XYZ Orientations
  • Versions Available with Adjuster Screw, Micrometer, or Differential Adjuster
  • Wide Range of Compatible Actuators (See Actuators Tab for Details)
  • Sixteen 1/4"-20 (M6) Tapped Mounting Holes

The PT series of translation stages have a 1" or 25 mm (model dependent) translation range and feature hardened steel linear bearings for precision motion and long life. These translation stages are available preconfigured (see note below) 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" 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

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.


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.

PT Series Mounting Adapters


* Build XY and XYZ Configured Stages
* Angle Bracket for Vertical Mounting

The PT101 and PT102 are adapter plates designed for the PT Series of translation stages. The PT101 is a universal base plate with slots on the side that enable obstruction-free mounting onto an optical breadboard. This base is ideal for XY or XYZ multi-axis configurations where the standard counterbores in the middle of the stages are obstructed.

The PT102 is an angle bracket that allows a PT Series stage to be mounted vertically. This is necessary in some XY and all XYZ configurations. The PT3 XYZ configured stages include both the PT101 and PT102 adapters. Please see the XYZ Assembly tab for more information on using these adapters to create a multi-axis configuration.
