Large Knob For Finer Adjustments

Compared to standard micrometers, the HR-1 has an extra-large diameter knob which provides 4x superior adjustment sensitivity. For fast coarse adjustments use the smaller diameter knob at the end of the screw.

High-Resolution Engraving

The engraved scale of the HR-1 allows position readings directly in units of 2 µm. This is 5-times higher resolution than most standard micrometers.

Mechanical Compatibility

The HR-1 micrometer, shown mounted to the 462-XZ linear stage, has an industry-standard Ø3/8 inch (9.5 mm) mounting barrel. The large diameter knob, however, restricts compatibility with some of our stages. For any questions about mechanical compatibility, please contact Newport.
