Micrometer Linear Actuator with manual adjustment knob

Click For Summary
SUMMARY

The discussion focuses on the need for a linear actuator with a handwheel pulse generator for controlling the Z-axis motion in an optical assembly process. Users are exploring options from Thorlabs, Zaber, and Edmunds, specifically looking for actuators that allow for selectable resolutions per count of the handwheel (1µm, 10µm, or 100µm). The goal is to replace manual micrometer handles with an automated solution that includes a handwheel for precise control. Recommendations include checking compatibility with existing Thorlabs translation stages and exploring CNC machine handwheels for potential solutions.

PREREQUISITES
  • Understanding of linear actuators and their applications in optical assembly.
  • Familiarity with Thorlabs translation stages and their specifications.
  • Knowledge of handwheel pulse generators and their resolution settings.
  • Basic concepts of CNC machinery and compatibility considerations.
NEXT STEPS
  • Research Thorlabs linear actuators with handwheel options for Z-axis control.
  • Investigate Zaber actuator models that may meet the specified requirements.
  • Explore the compatibility of CNC machine handwheels with existing optical assembly systems.
  • Review user manuals and specifications for Thorlabs translation stages to ensure proper integration.
USEFUL FOR

This discussion is beneficial for optical engineers, automation specialists, and technicians involved in precision assembly processes who are seeking efficient actuator solutions for Z-axis control.

I'm trying to put together an automated system for an optical assembly process. The base unit consists of a set of three-axis Thorlabs translation stages and manual micrometer handles for adjustment in X Y and Z.

I need to control the Z axis motion with a linear actuator instead of the manual adjustment of the micrometer handle. Thorlabs, Zaber, and Edmunds all sell actuators to do this. However, to move the actuator, you need to press/click a button on the controls to jog the actuator in a certain direction.

I would like an actuator that has a handwheel pulse generator to control the linear displacement of the actuator - preferably with select-able resolutions per count of the handwheel (i.e. one count = 1um, 10um, or 100um of linear displacement).

Does anyone know of such a system I could purchase off the shelf? It could be a self contained actuator with an adjustment knob on one end, or a combination actuator and controller unit.

There are hand wheels for CNC machines. Not checked compatability with your requirement..
