Initially developed for the semiconductor industry to measure photoresist.
A stylus profilometer now has a wide range of applications.
A diamond tip stylus is lowered onto the substrate with a certain low force.
The sample stage is moved and the stylus tip deflection is measured with an LVDT.
Step Height, Roughness, Waviness & Thin Film Stress can be measured.
