Thorlabs' Long Travel Vertical Translation Stages have been developed to accurately position optomechanical systems with moments as high as 150 in-lbs (16.9 N•m) at a recommended load of 50 lbs (23 kg). These stages are constructed using dynamically damped Ø1.5" posts to minimize mechanical vibration and ringing, making them ideal for alignment-sensitive applications.

VAP4 Stage Supporting an Aluminum Breadboard and an Optical System

The VAP4(/M) and VAP10(/M) Vertical Stages allow for 4" (101.6 mm) or 10" (254 mm) of translation, respectively. The fine adjustment knob on the top of each stage can be actuated by hand or with a 3/16" (5 mm) hex key or balldriver to achieve a motion of 0.05" (1.27 mm) per revolution. The torque required to actuate the fine adjustment knob increases with the load on the stage. For coarse adjustment over a long travel range, the stage features a quick-release button. Holding down the button disengages the stage from the lead screw and allows the position of the mounting plate to be adjusted by hand.

A pin attached to the back of the stage by a ball chain can be placed in a quick-release lock to prevent the use of the coarse adjustment feature. We recommend keeping this locking pin engaged at all times except for when using the coarse adjustment. Both the quick-release button and the locking pin can be seen in the image above. Two bumpers on the base plate of the stage help to minimize damage if the mounting platform is dropped during coarse adjustment with the quick-release mechanism. Once the required stage height has been set, two included C15QR handles can be used to lock the post clamps holding the mounting plate for extra stability.

The translating vertical 3" x 6" (76.2 mm x 152.4 mm) mounting plate has an array of thirty-three 1/4"-20 (M6) and thirty-one 8-32 (M4) tapped holes. An Aluminum Breadboard can be attached to this plate using 90° mounting adapters (such as the AP90 or AB90), as shown in the photo to the left. The base plate of the stage features six linear counterbored slots and one counterbored hole for 1/4" (M6) mounting hardware. In addition, two counterbored 1/4" (M6) slots on a Ø2.00" (50 mm) circle are provided for rotational positioning. For other high load vertical translation applications, we also offer a selection of Lab Jacks.

Is it possible to turn the base plate 180 degrees? So that if you mount something on the stage you can move it all the way down without touching the base? Is it possible to have it longer the stage ? (maybe 350mm or more?)

Hello, thank you for contacting Thorlabs. Flipping the mounting base is possible, we've offered this as a custom several times before. As for the longer travel, that would be limited by the lead screw. Unfortunately, we are currently limited to 10" travel. I will reach out to you directly to discuss your application.

Hej You name a max. moment of 16.9 Nm in the specs. For my calculations: Where do I have to apply it? 1) Where the posts touch the base-plate? 2) On the mounting plate? Thanks!

Response from Tim at Thorlabs: Thank you for your question. The moment load is measured from the mounting plate, not the base of the posts. We have updated the web with this information.

Dear Sir or Madam Is it possible to have a vacuum compatible (10^(-8) mBar) version of this stage?

  • One-Piece Aluminum Construction for Excellent Rigidity
  • Parallel and Perpendicular to Within 0.002" (0.05 mm)

The AP90(/M) and AB90 Right-Angle Adapters are ideal for mounting aluminum breadboards on the VAP4(/M) and VAP10(/M) Vertical Translation Stages. The AP90(/M) plate provides four 1/4"-20 (M6) clearance slots, seven 1/4"-20 (M6) tapped holes, and two 1/4"-20 (M6) counterbores on one face. The other face contains two 1.30" (34 mm) long, 1/4"-20 (M6) clearance slots and two 1/4"-20 (M6) counterbores for attaching it to the mounting plate of these stages. The AB90 Right-Angle Bracket has two counterbored slots at 90° for 1/4" (M6) mounting hardware.

For alternative 90° mounting options, please see our full selection of 90° Mounting Adapters. We also offer 45° and 30°/60° mounting plates.
