Micrometer Linear Actuator with manual adjustment knob

  1. Jun 16, 2015 #1
    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.

    These are the actuators: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1883
    These are the translation stages: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=706
