What is a profilometer used for?
A profilometer is used to measure the surface roughness and contour of a material, ensuring precise control in manufacturing and quality assurance.
What are the types of profilometers?
Profilometers can be classified into contact, non-contact, optical, and tactile types depending on their measurement method.
How do optical profilometers differ from contact profilometers?
Optical profilometers use light to measure surfaces, avoiding direct contact, while contact profilometers physically trace the surface with a stylus.
Can profilometers measure 3D surfaces?
Yes, 3D profilometers provide detailed analyses of complex surfaces by capturing height profiles across a surface area.
