Nanomotion´s Z-Axis Auto Focus Stage

Nanomotions’s Z axis Auto Focus Stage is designed specifically to meet the demanding needs of focus applications, making incremental moves in milliseconds. The stage utilizes a high resolution encoder, with a ceramic servo motor sized appropriately for the user load. A spring counter balance provides for the ability to manage larger loads in a vertical orientation, without excessive motor force.

The Z axis stage is capable of meeting the needs of the most aggressive Biomedical and Semiconductor focus applications. While the stage technology can provide long travel, it can make focus moves in the range of 1 to 10 microns in 5 milliseconds, settling to 100nm.

The Z Axis stage provides the highest level of motion performance in the smallest package. Nanomotion’s state-of-the-art ceramic servo motor technology optimizes move time, settling, and position stability. Features are for example ceramic servo motor with travel to 25mm, high resolution from 10nm to 100nm (1nm optional), zero backlash with direct drive, high speed move & settle for focusing operation, superior position stability and zero power consumption at rest, position holding without power provides optical stability and reduces thermal drift and easy add-on mounting to standard microscopes.
