TPI Adjustment Screws
Small Scale Micrometers
The SM series uses our precision 100TPI
adjustment screws for submicron resolution. These small micrometers
are designed specifically for our 50.5cr, 100.5cr and 150.5cr series stages. The adjustment dial is marked
with 20 individual graduations (.010-inch per revolution) and can easily
resolve .0005-inch [10μm]. They are available in 0.5-inch and
1.0-inch travel versions.
The SDM series differential
micrometers use a combination of our precision adjustment screws for the
fine adjustment section that give 20μm per revolution on the non-rotating
tip with 1.0μm resolution. This provides true
sub-micron motion in a manual actuator.
range of the differential section is 500μm, combined with a coarse travel
range of 0.25-inch and 0.5-inch. The coarse travel section can be
locked and has a scale for reading rough location within the travel range.
These small micrometers are designed specifically for our 50.5cr, 100.5cr
and 150.5cr series stages.
