INTRODUCTION:

The DektakXT stylus surface profiler is an advanced thin and thick film step height measurement tool, which takes measurements electromechanically by moving a diamond-tipped stylus over the sample surface according to a programmed scan length, speed, and stylus force. In addition to profiling surface topography and waviness, the DektakXT system measures roughness in the nanometer range. Furthermore, three-dimensional morphology image can be obtained by multi-line scanning. The apparatus costs 0.3 million Yuan.
