Focus Variation Microscope

The Focus Variation Microscope from Atometrics is designed for high-precision, non-contact 3D surface inspection. Using focus variation technology, it captures sharp images at different focal planes and reconstructs detailed 3D surface profiles, enabling accurate measurement of roughness, steps, and complex geometries.

Measurement Principle

Atometrics focus variation microscopes operate by scanning the sample at multiple focal depths. The system combines in-focus areas from each layer to create a fully focused image, then reconstructs a 3D surface model. This method allows accurate evaluation of surfaces with steep slopes, high roughness, or complex topography without physical contact.

Key Features

• High-resolution 3D imaging: Captures micro- and nano-scale surface features accurately.
• Non-contact measurement: Protects delicate surfaces and ensures repeatable results.
• Surface roughness analysis: Provides quantitative roughness parameters including Ra, Rq, and Sa.
• Step height and contour measurement: Measures precise geometric dimensions on complex surfaces.
• Automated data processing: Includes reporting, statistical analysis, and multi-sample evaluation.

Applications

Atometrics focus variation microscopes are widely used in:

• Precision mechanical component inspection
• Surface roughness and coating evaluation
• Optical lenses and mirrors inspection
• Material science and microstructure research
• Semiconductor and MEMS surface analysis
