Features

  • 1" (25 mm) Travel
  • Available with Differential or Micrometer Drive
  • Rugged, Thermally Matched, All-Steel Construction
  • Right- or Left-Handed, XYZ Configurable
  • Extremely Durable and Long Lasting

The LNR25 series of stages offer excellent stability and high load capacity, making them ideal solutions for all translation applications. Their rigid, all-steel construction and heavy-duty cross-roller bearings provide uniform performance over the entire range of motion. The LNR25M is fitted with the imperial 150-811ST micrometer, which provides 1" of travel, 0.025" of translation per revolution, and 0.001" graduations. Its metric counterpart, the LNR25M/M, is fitted with the 150-801ST micrometer, which provides 25 mm of travel, 0.5 mm of translation per revolution, and 0.01 mm graduations.

For applications that require increased resolution, consider the LNR25D, fitted with the DM12 differential actuator. The coarse adjustment uses a 0.5 mm pitch thread that provides 0.013" (318 µm) of translation per revolution with a range of 1" (25 mm). The coarse adjustment can be locked using a thumbscrew located on the mounting collar. The differential adjustment, which features a vernier scale with 0.5 μm graduations, provides 0.001" (25 μm) of translation per revolution over a 0.01" (250 μm) range.

Designed with the highest quality linear rails available, the performance is further enhanced by using thermally matched materials that ensure stable, smooth performance. A locking screw located on the opposite side from the actuator optionally holds the moving stage in place. In addition to the manual actuator options here, a stepper motor translation stage (LNR25ZFS) is also available. The LNR25 series of stages is also compatible with our slim ZST225B Stepper Motor Actuator. We also offer barrel adapters for select screw adjusters, making them compatible with the stages below.

Wide Range of Mounting Options
The TravelMax™ was designed with flexibility and functionality in mind. The top surface of the LNR25 stage, shown to the right, is equipped with an array of seven 1/4"-20 (M6) tapped holes to maximize the mounting options for moving components. Two through holes in the top platform give access to two 1/4-20" (M6) counterbored holes that allow the stage to be bolted directly to the work surface. The position of the actuator mounting blocks is easily reconfigured to allow left-hand or right-hand use.

The LNR25P1 base plate, shown to the left, provides additional mounting options and provides extra clearance between the stage and the work surface. Counterbored clearance holes match up to the tapped holes in the base of the stage, permitting mounting in two orthogonal orientations. This plate is compatible with both the imperial and metric versions of the LNR25ZFS(/M) stage. The plate measures 65.3 mm x 90.5 mm x 10 mm (2.57" x 3.56" x 0.39") [L x W x H], ships with two dowel pins, and includes four alignment holes to ensure mounting orthogonality.

Multiple LNR25ZFS series stages can be bolted together in XY, XZ, YZ, or XYZ configurations for applications where movement is required in more than one axis. The LNR25P2 angle bracket, shown to the left, provides the vertical mounting necessary for movement in the Z direction. Again, this bracket is compatible with both the imperial and metric versions of the LNR25ZFS(/M) stage. The plate is shipped with four dowel pins and includes four alignment holes on each face to ensure orthogonality when mounting stages.

A Response from Sean at Thorlabs: Thank you for your feedback. I apologize that we do not specify a consistent set of specifications across our two product lines. I've spoken with the product engineers, and we will endeavor to test both sets of stages under the same conditions in the near future. We don't have your email address, but if you'd like us to contact you with a status update, please write us at techsupport@thorlabs.com.

You do a good job listing the specs of the cheaper aluminum stages but on these expensive steel stages so many of the specs are missing. I get the feeling they might not be as good as the aluminum stages even with the roller bearings. Why should I spend more for a stage which might be inferrior to the aluminum stages. I see the angular deviation is 244 urad which is not that good for the price. The alum stage had 250 urad for much less. Do you see my point?

Response from Buki at Thorlabs: Thank you for your feedback. We have already contacted you with this information.

Please send me the solidworks file of LNR25D stage. I have solidworks 2010 and it says that i cant open as its a future verison. Thanks karthick

Response from Javier at Thorlabs to acable: Thank you very much for your feedback. We will add a photo of the LNR25P2 mounting plate which shows the 8 alignment pin holes (4 on each axis) shortly.
acable  (posted 2011-06-28 15:40:29.0)
The base plate appears to have alignment pins, but there is no indication that the angle bracket has similar alignment features. Please carify how the stage can be bulit up into a 3 axis system ensuring the orthogonality of the 3 axis. Customer Email: acable@thorlabs.com

Response from Buki at Thorlabs: Thank you for your feedback. Below is our measured angular deviation data: Pitch: 53 µrad Yaw: 244 µrad We will work on updating our website with this information. Please contact TechSupport@thorlabs.com if you have further questions.

What is the angular deviation of these stages?
jjurado  (posted 2011-03-11 10:36:00.0)
Response from Javier at Thorlabs to patrick.parkinson: Thank you for submitting your inquiry. We can certainly offer the LNR25 stage without the micrometer or differential drive. Keep in mind that this stage is compatible with the ZST25B motorized actuator, which includes a 3/8" diameter barrel, whereas the regular ZST25 is 1/4"-80 threaded. I will contact you directly for processing a formal quotation.
patrick.parkinson  (posted 2011-03-11 06:52:46.0)
Is it possible to purchase this stage with no drive? I already have some ZST 25 type motorised translation stages, I would like to use these with the LNR25 translation stage (as long as it is compatible). Thanks.
