Laserscanner LAS-20

3D Profilometer

The compact and easy-to-use measuring device especially for dental materials research.

SD Mechatronik introduces with the new LAS-20 a precise, extremely compact and easy to use measurement instrument for dental materials research. The main focus in the course of the development was on the surface analysis as well as on the comprehensive data export. The vertical sensor resolution is up to 0,8 µm. Thus, fine structures such as cracks and traces of movement can be resolved.
The analysis of the abrasion depth and volume based on endurance testing is an essential component in the evaluation of materials. Samples have previously had to be pre-treated for the optical measurement. The additional applied layer modifies the surface of the sample, so that it is no longer available in the original state. In addition, the pre-treatment or else the making of a replica constitute additional work. These steps can now be completely eliminated thanks to modern measurement sensors!

Simply insert the sample into the scanner, define the measurement field and start scanning!

Almost all samples that come in question for stress testing can be examined:
  • Composite materials
  • Natural teeth
  • Antagonists made out of ceramic, metal or steatite
  • Crowns
The insertion of the samples is carried out quickly and without problems, since a self-centering mount is capable of accommodating almost any geometry shape.

The user interface is intuitive to use and concomitantly allows you to quickly set all relevant parameters. The measurement field is defined with the built-in camera. The adjustable LED lighting provides a high-contrast image of the sample. The camera image can moreover in addition to the scan data, also be stored as a BMP or JPG. The user is guided on a step by step basis through the program so that only little time is required for the initial training. All screen views can be stored as screen shots for documentation purposes. The software can be updated via Internet.

Further steps such as the definition of the measuring field are not necessary. Advanced users have the option to adjust many sensor parameters. This includes, for example, median filtering to better emphasize structures or the setting of the measurement gain in order to keep the depth of penetration of light into the material - and thus scatter - as low as possible. This means that even difficult surfaces such as high gloss can be analyzed.
