Precise measurements for engine research and development
We offer innovative optical characterization and visualization methods for fuel sprays and injection systems. LaVision’s SprayMaster geometry software package in DaVis determines structure and geometry data from light section as well as globally illuminated spray images. Depending on the optical arrangement, DaVis provides data on the spray pattern (radial sections) or on the jet shape (axial sections). When analyzing multi-hole nozzles, the geometry data is determined separately for each spray jet.

SprayMaster
The development tool for efficient injection processes
The SprayMaster is the modular high-performance system for spray research on injection systems with fuels of all kinds. Its optical measuring methods enable detailed analysis of the spray pattern and spray cone in order to optimize product quality as early as the development phase. With its high flexibility and expandability, the system adapts to individual requirements in R&D – for scientifically sound and efficient product development and optimization.
System & components
The SprayMaster, as the basic equipment concept, forms the central platform of your innovative system. With universal mounting, injection systems and other applicators of various shapes and sizes can be securely positioned. Measurements are made using backlit imaging, light section technology and shadowgraph analysis, which enable complete characterization of the spraying process. The system is specifically designed for use in research laboratories and product development environments.
Measured variables & analysis areas
Spray pattern geometry:
The spray pattern is crucial for the function and efficiency of an injection system. The SprayMaster enables the detailed analysis of the homogeneity, size and shape of the spray pattern to ensure that the injection of a wide range of fuels has a uniform and controlled distribution:
- Spray pattern area and equivalent diameter
- Mass circle diameter according to SAE definition
- Center of gravity relative to the nozzle axis
- Shortest and longest radius in the spray pattern
- Diagrams of the radial and angular distribution of the fuel spray jet
Spray cone analysis:
The system precisely measures the cone angle, penetration depth and symmetry of the fuel spray jet to ensure optimum spray distribution for various applications:
- Spray cone angle at a specified distance from the nozzle

ParticleMaster
Particle & droplet size analysis of fuels
The ParticleMaster specializes in the precise analysis of droplet size distribution and particle density. Its LED-based measurement technology provides reliable data for optimizing a wide range of injection systems and technologies.
- Droplet size & distribution – Detailed analysis of particle density & droplet sizes
- Particle homogeneity – optimizing uniformity and density for efficient power generation
System & components
The ParticleMaster uses LED-based shadowgraph imaging for high-resolution droplet analysis. The light source and sample are placed outside the spray area, preventing electrical components from coming into contact with the fuel. 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.
The compact design allows easy integration into your laboratory and test bench environment.
