FIELDS OF APPLICATION
Even the best 3D Scanners sometimes need matting spray for quality data collection.
As we are dealing with optical technologies, light needs to be projected on and/or reﬂected off the surface back into the detector of the scanner. In case of a transparent surface, however, the light will go through the surface instead of being reflected by the same. In consequence, the scanner is not able to capture the surface structure.
In case of reﬂective parts, such as a mirror, the light beams will be reﬂected in a focused way instead of in a diffused way. This means that the chance of a beam hitting the reﬂector of the scanner is greatly reduced and the scanner will only capture a fraction of the reﬂected light beams.
When the object to be scanned has deep pockets, the scanner receives a reﬂection from the walls of the pocket onto the bottom. This causes disturbance in the pattern of the light manifesting in the scan as “artifacts” or bad data.
High quality and accuracy
When quality and accuracy are important, you might want to apply spray to remove as much as possible all the causes like colour differences, differences in reflection, texture, etc.
The use of spray creates a matte, white coat reducing reflection and other inhomogeneities and thus provides perfect scanning condition.
In general, matting sprays used in 3D metrology for antireflective coatings can be classified into the following two product groups:
- Surface remains white after scan
- Cleaning required or disposal of scanned object
- Coating evaporates automatically
- No cleaning after scanning required
- No pigment-contamination of laboratories, sensors, environments, scanners and users
