2-4 System Overview
Sensor Head and Stylus Assembly
A diamond-tipped stylus (see Figure 2-3) attached to the sensor head permits accurate two-
dimensional surface profiler measurements in a wide range of applications. In standard configuration,
user-programmable stylus force from 1 mg to 15 mg allows profiling on soft or hard surfaces.
A variety of available stylus tip sizes are available to fill a broad range of measurement applications.
Each tip comes in its own protective case.
NOTE – The DektakXT system comes with a stylus exchange tool that allows you to safely
exchange one stylus for another without damaging the delicate tip.

Sample-Positioning Stage
Available sample-positioning stages and sample fixtures (chucks) are discussed in Stage
Configurations on page 2-2.
Scan Stage
The direct-drive scan stage accelerates measurements by reducing the time between scans. This
allows for the generation of large 3D maps or long scans for measuring stress.
Electronics
The DektakXT system includes a power supply adapter with an input voltage 100 - 240 VAC
(see
Figure 2-5). This unit sends power to the various system components.
WARNING
Do not remove the hood and attempt to service the components of the
yourself. Instead call Bruker Customer Service. Failure to heed this warning
can result in damage to delicate equipment.
