Imaging Gantry

Imaging Gantry

Challenge: Customer needed to shorten focusing times in their next-generation system. To accomplish this, they required a high speed and high straightness stage that fit in their existing package. Flatness was not critical.

Solution: Motion Solutions utilized THK SHS linear bearings, Akribis linear motor, Renishaw Quantic encoder and Motion Solutions-designed machined parts and extrusion to produce a system that included these features:

  • Custom extrusion for high strength and low weight on top Y-axis
  • Dual-driven bottom X-axis for higher load capacity
  • Special system alignment for straightness
  • Stainless steel optical encoder for positioning
  • Linear motor as drive mechanism for speed and precision
  • Custom Z-axis for camera positioning

Result: Motion Solutions was able to provide a high precision system, reducing imaging times with high-speed actuators including on the Z focus stage and a sub 18 arc-second straightness error in the dual X-axes over a 390mm stroke. Results were quantified using laser equipment.

Our Design Process

“It’s really important to thoroughly understand the application. We would start by reviewing the statement of work or application information that the customer provides, and then we would have a consultative meeting to make sure that we really understand how the system should function, and all of the nuances that are associated with it.”
