Roughness Profiler

The Roughness Profiler by Atometrics is designed for precise, non-contact measurement of surface roughness and texture. Combining optical interferometry and high-resolution imaging, it provides accurate quantitative evaluation of surface characteristics at the nanometer scale.

Measurement Principle

The Atometrics roughness profiler operates based on optical interferometry or confocal microscopy principles. A focused light beam scans across the sample surface, and the reflected signal is analyzed to reconstruct the microtopography. This method enables accurate evaluation of roughness parameters such as Ra, Rq, Rz, and Sa, providing a complete picture of the surface morphology without touching the sample.

Key Features

• Nanometer precision: Measures surface roughness with extremely high vertical resolution.
• Non-contact optical measurement: Eliminates probe wear and prevents surface damage.
• Comprehensive roughness parameters: Supports ISO-compliant 2D and 3D roughness standards.
• Fast scanning capability: Suitable for production inspection and laboratory research.
• 3D visualization and analysis: Provides detailed surface maps and automated data reports.

Applications

Atometrics roughness profiler systems are widely used in industries that demand precise surface characterization:

• Semiconductor wafer and MEMS surface analysis
• Optical lens and coating texture evaluation
• Machined metal and precision tooling inspection
• Automotive and aerospace component finishing control
• Material science and nanostructure research
