SM Series Vernier Micrometer Heads
SM Series Vernier Micrometer Heads
SM series vernier micrometers are our most popular manual actuators and are the standard drives for most of our popular manual stages and mounts.
- Standard Ø3/8 inch (9.5 mm) mounting barrel
- Exceptionally smooth movement
- Vernier scale allows position readout with 1 µm resolution
- Compatible with most Newport translation stages and mounts See All Features

Specifications
Features
Read Between the Lines
The Vernier scale allows measurement in between two of the increments on the main scale and therefore lets the user measure more precisely than what could be done by rough estimation. These micrometers have 0.5 mm pitch (50.8 TPI) threads and read directly in increments of 10 µm, with vernier reading of 1 µm.
Left-handed Micrometers
The SM-13LH is a left-handed version of the SM-13. Compared to a standard micrometer, the spindle on a left-handed micrometer travels in the opposite direction during operation. For example, the spindle on the SM-13LH will retract when the knob is rotated clockwise. This left-handed micrometer is made to be used on stages where the micrometer mounting is on the moving (top) platform of the stage.
Standard 9.5 mm Mounting Interface
All SM series micrometers have the same 9.5-mm mounting interface making them both interchangeable with other micrometers and compatible with the Newport stages listed below.
