Manufacturer’s Description:

When manual resolution of much less than one micrometer is needed, a differential screw is recommended. A differential micrometer uses a spindle with two opposing screw threads of slightly differing pitches. The mechanism allows extremely small adjustments using commonly available screws.

The DM-13 combines 13mm of coarse travel range with 0.2 mm fine adjustability in a single micrometer. Use the knob at the back for coarse positioning like a classical micrometer drive. When done, use the other knob for fine tuning your position with 0.07 µm adjustment sensitivity. The motion of the DM-13 is exceptionally smooth and crisp, without tightness or difficult turning. DM-13 provides excellent linearity and absolute accuracy better than 1%, and its unique design exhibits no harmonic motion errors typical of conventional differential screws.
