Manual Actuators

Manual actuators are the mechanical interface situated between your hand and the stage or mount you are aligning.  Essentially all manual stages and mounts have some type of manual actuator. They convert rotational motion into high-resolution linear motion by way of a helical thread.  Due to fine pitch threads, the resolution achievable with most manual actuators is easily in the range of 1 to 10 um.  With differential micrometers the resolution is even better, like 10X better. Manual actuators are available in several different types including familiar micrometers heads, adjustment screws, differential micrometers, digital micrometers, and vacuum compatible micrometers.  If one of our many catalog adjusters does not meet your requirements, send us a request for a custom one.
