The S neox 090 3D optical profilometers is used to measure roughness, step height, texture, geometry, thickness, and more for any material.
Confocal
Confocal profiler has been developed for measuring the surface height of smooth to very rough surfaces. Confocal profiling provides the highest lateral resolution, up to 0.15 μm line and space. High NA (0.95) and high magnification (150X) objectives are available to measure smooth surfaces with steep local slopes over 70° (for rough surfaces up to 86°).
Interferometry
Interferometry has been developed to measure the surface height of very smooth to moderately rough surfaces, achieving same system noise at any magnification. For PSI, it can achieve system noise better than 0.01 nm.
Sensofar Focus Variation
Thin film measurement
The Film measurement technology has been developed for measuring the thickness of optically transparent layers. Sample evaluation spot diameter is dependent on the objective magnification which can be as low as 0.5 μm and up to 40 μm.
