From overspray to perfection -
Innovative control systems that pay off
Optical quality control for perfect paintwork and coatings
Perfectly applied paint sprays, paints and coatings are essential for the quality, functionality and durability of products. Faulty spray patterns, uneven coating thicknesses or excessive material consumption due to overspray not only lead to visual defects, but also to considerable economic losses. With LaVision’s optical analysis methods, all application processes can be visually recorded, evaluated and precisely optimized. Our modular measuring systems enable end-to-end quality assurance – from the spray can to robot-controlled high-performance painting.

More InformationParticleMaster inspex - Precise droplet and particle analysis for quality testing
The ParticleMaster inspex provides a detailed analysis of droplet size and particle distribution in paint sprays, paints and industrial coatings. Thanks to LED-based measuring technology, it ensures uniform application and optimum material utilization.
System & components
The ParticleMaster inspex uses LED-based shadowgraph imaging for high-resolution droplet analysis. The light source and sample are placed outside the spray area, which means that electrical components do not come into contact with the spray. The high-resolution camera system in the sample precisely records the droplet size, speed and shape. The dynamic image analysis (DIA) evaluates the recorded images and guarantees operator-independent, reproducible results in the shortest possible time.
Measured variables & analysis areas
- Droplet size distribution: (DV10, DV50, DV90) for uniform paint application
- Particle concentration: Number and mass concentration within the spray jet
- Particle homogeneity: shape, density and uniformity across the spray cross-section
