3D surface analysis - laser scanning microscope (LSM)

The laser scanning microscope (LSM) in the encontec test laboratory enables non-contact, high-resolution recording of surface and microstructures based on confocal laser scanning technology. The measurement is carried out without moving the sample, which ensures reproducible and distortion-free topography recording even with sensitive or structured components. Thanks to the available measuring range of up to 100 mm diameter and a height resolution in the sub-nanometer range, the system is suitable for detailed analyses in quality assurance, damage analysis, research and product development.

Laser scanning microscope (LSM) - Precise 3D surface analysis

The laser scanning microscope (LSM) in the encontec test laboratory enables non-contact 3D surface measurement with sub-nanometer resolution - ideal for sensitive, complex or high-precision components. The measurement is performed without sample movement, which minimizes distortions and measurement errors.

Technically precise 3D surface characterization

Confocal laser scanning microscopes capture the surface point by point or line by line in different focal positions. This creates a high-resolution 3D elevation model with high lateral and axial resolution.

 

In contrast to 2D profile measurements, area-based recording enables the reliable identification of local topographical structures.

 

Typical analyzable characteristics:

  • Micro- and nanostructures
  • 3D roughness parameters in accordance with relevant standards (e.g. ISO 25178)
  • Pores, depressions and material inclusions
  • Scoring, scratches and tribological marks
  • Particles and local material irregularities
  • Functional surfaces (plateaus, pockets, microchannels, lubricating film pockets)

 

Relevance of 3D roughness parameters in practice

Compared to 2D profile measurements, 3D roughness parameters provide significantly more comprehensive information on the functional behavior of a surface. They are crucial for the evaluation of:

 

  • Friction and wear behavior
  • Tightness and susceptibility to leaks
  • Running-in behavior and lubricating film formation
  • Load capacity and contact mechanics
  • Microstructured functional surfaces (e.g. plain bearing surfaces, sealing surfaces)

 

This data supports the optimization of production processes, the monitoring of product quality and the analysis of error causes.

 

Technical advantages of the LSM at a glance

  • Non-contact, non-destructive measurement - no mechanical influence on the surface
  • Measurement without sample movement - ideal for sensitive or unstable components
  • Sub-nanometer height resolution - precise detection of the finest structures
  • Areal measurement data - complete 3D topography instead of one-dimensional profiles
  • High repeatability due to stable optical scanning
  • Fast data acquisition for efficient testing processes
  • Comprehensive 3D evaluation software for topography, profiles and functional parameters
  • Robust, low-maintenance system for continuous industrial use
