Sample Preparation

Surface patterns on the test specimen are essential for Digital Image Correlation (DIC). If there are no sufficiently recognizable natural patterns on the surface of the specimen or if the surface is highly reflective, it is recommended to make use of artificial patterns, e.g. produced by spraying paint.

Speckle Pattern Toolkit

The StrainMaster Speckle Pattern Toolkit is an easy-to-use alternative to spray cans and conventional stamps.
A special foam roller allows the application of a particularly fine speckle pattern similar to that provided by aerosol paints. On larger areas patterns can be produced with the porous, soft rubber sponge. Multiple applications of the sponge to the specimen surface increases the density of the speckle pattern.
The paint used for the StrainMaster Speckle Pattern Toolkit is water-based with additives that ensure it adheres to plastic and metal surfaces. The paint is completely non-toxic and easily cleaned from the surface with soap and water!

Airbrush Kit

The Airbrush Kit that LaVision offers consists of a powerful compressor, two airbrush guns for the application of fine to medium patterns and a wide range of accessories.

The Airbrush Kit uses a powerful, quiet and oil-free working compressor with a 3 liter air pressure tank. The compressor runs according to the demand of the air tank based on the automatic pressure control of the air tank.
