Manual Actuators

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.

  • Fine-pitch Screw Adjusters

    Description

    OptoSigma Fine Pitch Screw Adjusters are offered as a replacement or in place of our standard micrometers. The precision screws are turned from high grade stainless steel and are supplied with a matching brass nut designed to fit our stages and mirror mounts. They are lockable by means of a set screw on the nut using an Allen wrench. The M6.25 screws are designed to drive OptoSigma’s 40mm, 60mm, and 65mm stages. The M4-P0.25 screws are designed for use with the 25 mm stages.

  • Right-Angle Micrometer Heads

    Description

    OptoSigma right-angle micrometers are unique. They can be used in place of standard micrometers on our manual stages to enable top or angled adjustments. They incorporate a 90-degree angle pivot mechanism. Please contact our application engineers to answer any questions about how these right-angle micrometers can be mounted and utilized on the stage of your choice, or, stand-alone in your application.

  • Sub-micron Worm Drive Micrometer Heads

    Description

    OptoSigma’s Sub-Micron Worm Drive Micrometer provides superior alignment capability vs. conventional micrometers.  They are relatively low cost and offer much higher resolution. The resolution of the Sub-Micron micrometer is 0.5 micron for the entire 13mm of travel range. This micrometer can replace our standard micrometers to achieve higher sensitivity for any optical-mechanical devices. Replacing the micrometer is relatively easy.  Both Flat and Ball tips are available.
