Manual Drives, 1/2" Differential Actuators




  • Coarse & Fine Adjustment
  • Standard 3/8" (9.5 mm) Mounting Barrel

These differential adjusters are designed for use on stages with a 9.5 mm (3/8") mounting clamp.
The DRV304 is ideal for updrading our RB13M 3-axis RollerBlock stage to differential drives. The DM10 is for use with our MT1 and MT3 stages.

 


Manual Drives, 1/2" Differential Micrometer

  • Designed for Use with Our RollerBlock Stages
  • 1/2" (13 mm) Coarse Travel
  • 5.0 µm Coarse Resolution
  • 300 µm High Resolution Differential Travel
  • 0.5 µm Differential Resolution
  • Ø3/8" Mounting Barrel

The DRV304 Differential Micrometer uses a unique mechanism that converts a relatively large displacement into a relatively small displacement of the center fine adjustment spindle. The design has the additional benefit of providing a uniform, smooth feel that is largely independent of loading. Coarse adjustment is provided via a knurled knob, while the differential adjuster features a large rubber grip which adds to the overall sensitivity of the unit. The coarse adjustment knob gives 13 mm of total travel with 5.0 µm resolution while the differential knob provides 300 µm of total travel with 0.5 µm resolution. The Ø3/8" mounting barrel is compatible with a host of standard mounting equipment.

 

Manual Drives, 1/2" Differential Adjuster

  • 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.
