Abrasion measuring device for measuring abrasive wear of surface of e.g. dental prosthesis, has module carrier arranged perpendicular to first axis, which is provided perpendicular to second and third axes

摘要

The device has a sample retainer (5b) for retaining a sample. A module carrier (4) is arranged parallel to the sample retainer. A CMOS-camera (8) and a laser sensor (12) are arranged at the module carrier. The sample retainer and the module carrier are movable relative to each other along a first axis (X) and/or a second axis (Y), which stays perpendicular to the first axis. The module carrier is arranged perpendicular to a third axis (Z), which is provided perpendicular to the first and second axes. A LED (9) is arranged at the module carrier. An independent claim is also included for a method for measuring an abrasive wear of a surface of a sample.
