Presentation Highlights

Expert Answers to Live Audience Questions:

Q: When operating in film mode, how does the ContourX-500 respond to "islands" of film (film and substrate in the same FOV)?

   

Q: Can the ContourX-500 measure the thickness of 2+ layers of a transparent or translucent film?
Q: What roughness standard is used to validate the roughness values/calibrate Bruker's 3D Optical Profiler systems?

   

Q: How does the refractive index impact optical proflers' thickness calculations?
Q: How could optical profiling be used to measure the thickness of an opaque film without any step?
