Atomic Force Microscope

Make / Model : 

Dimension 3000


The Dimension 3000 consists of a rigid stage mounted on granite block, and features a beam deflection SPM head and an on-axis video microscope. A flexible cantilever, with a sharp probe, is mounted on one end of a culindrical piezoelectric tube. The piezo tube is rigidly mounted near the top of the microscope.

Voltages applied to teh X and Y electrodes on the piezo tube deflect the tube horizontally to produce precise raster scan over teh sample surface. The vertical height of hte probe is controlled by a voltage applied to the Z electrode of the piezo tube. A stepper motor coupled ot a lead screw translates a roller slide to which the sample is attached. Samples may be up to 8 inch diameter and 0.5 inch thick.
