• Designed Specifically for use in our 1/2" Travel Stages
• Coarse Adjustment: 1/2" (12.7 mm)
• Fine Adjustment: 250 µm Range, 25 µm per Revolution

The DM10 Differential Adjuster uses two internal leadscrews; one pushes the center spindle forward at 400 µm per revolution, and one pulls it back at 375 µm per revolution. The resultant total forward motion of the center spindle is just 25 µm per one complete revolution of the graduated knob. Each graduation of the fine control knob is 0.5 µm. The coarse adjustment provides 1/2" of travel with a screw pitch of 0.5 mm, which is lockable via a thumbsrew located on the mounting barrel. Also available is the DM12 1" Differential Adjuster.
