Newport MKS Lockable Differential Micrometer, 13 mm Coarse, 0.2 mm Fine, 11 lb. DM-13L

Description
The DM-13L Differential Micrometer provides sub-micron positioning combined with a coarse travel of 13 mm. The design incorporates a standard micrometer with a high-resolution micrometer built around it. Coarse positioning, provided by the knob at the end of the micrometer, enables rapid translation with a sensitivity of 1 μm. The fine adjustment knob, closest to the positioner, allows ultra-fine positioning over 0.2 mm of travel, with 0.1 μm sensitivity. 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. Lockable Coarse and Fine Adjustments The DM-L Series is the first actuator where both coarse and fine travel can be locked with a single knob. Coarse positioning enables rapid translation with a sensitivity of 1 µm while the fine adjustment knob allows ultra-fine positioning over 0.2 mm travel, with 0.1 µm sensitivity. Compatible With a Wide Range of Newport Stages and Mounts DM-L micrometers have the industry-standard 9.5 mm mounting interface making them both interchangeable with other micrometers and compatible with Newport stages and mounts like those listed below. 461/462 Series 561/562 Series 423 Series 426 Series 460P Series 460A Series 401/406 Series RS Series GON Series

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.


Lockable Coarse and Fine Adjustments


The DM-L Series is the first actuator where both coarse and fine travel can be locked with a single knob. Coarse positioning enables rapid translation with a sensitivity of 1 µm while the fine adjustment knob allows ultra-fine positioning over 0.2 mm travel, with 0.1 µm sensitivity.
