Newport MKS Differential Micrometer Head, 13.0 mm Coarse, 0.2 mm Fine, 5 lb. Load DM-13

Description
The DM-13 Differential Micrometer offers sub-micron resolution in a unique design that achieves long range and fine adjustability in a single micrometer. The DM-13 has a 13 mm overall range with 0.2 mm fine adjustment range. It employs the same mounting bezel as our standard SM Series Micrometers, so it may be used to easily upgrade an existing instrument to provide, in most cases, a factor of 10 improvement in resolution. In effect, we have built a differential micrometer outside of a standard micrometer - a simple concept that is difficult to implement. The motion it provides is exceptionally smooth and crisp, without tightness or difficult turning. The 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. Differential Micrometer Drive 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 (P1 and P2). As the spindle rotates, the net travel of the micrometer tip is : 1/Peff = 1/P1 - 1/P2. This mechanism allows extremely small adjustments using commonly available screws. Exceptionally Smooth Motion The DM-13 combines 13 mm 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. Compatible With a Wide Range of Newport Stages and Mounts The DM-13 employs the same mounting bezel as our standard SM Series Micrometers, so it may be used to easily upgrade an existing stage to provide, in most cases, a factor of 10 improvement in resolution. The DM-13 is compatible with 461/462, 561/562, 423/433, 426/436, 460P, 460A, 401/406, RS and GON Series Stages as well as many modular optical mounts.
