The DM series differential micrometers provide ultra-fine, sub-micron positioning capabilities and coarse, long travel adjustments in a single device. In essence, the DM series micrometers are standard micrometers with a 0.05 mm pitch high-resolution micrometer built around it. Coarse positioning, provided by the control knob at the end enables rapid translation with a sensitivity of 1 μm. Then, by using the fine adjustment knob closest to the positioner, the position can be further optimized with a sensitivity of 0.1 μm over a limited travel range.
The large diameter knob allows more spacing between the increments making it easier to take measurement readings.
DM Series Micrometers are compatible with the following manual stages and mounts:
