Bruker Dektak 150
Primary Training Contact: 
Operating Procedures: 

The Dektak150 is an advanced surface texture measuring system which accurately measures surface texture below submicro-inch and film thickness to 1000μm.  Measurements are made electromechanically by moving the sample beneath a diamond-tipped stylus according to a user-programmed scan length, speed and stylus force.  As the stylus moves across the sample, surface variations cause the it to be translated vertically.  This corresponds to an electrical signal that gives a feedback of the appropriate step height.
