Precitec LR sensor extends capabilities of Leitz Infinity CMM to sensitive and inclined surfaces

Hexagon Metrology claims that with the Precitec LR white light sensor (lateral resolution) integrated into the measuring system, the Leitz Infinity 3D co-ordinate measuring machine is able to measure surfaces of any kind.
The Precitec LR sensor has an acceptance angle of 90° ±40° and therefore measure dimensions or profiles of even very sloping surfaces with high precision without contact or affecting the workpiece in any way.
In the future, the sensor technology also offers the potential to measure roughness and thickness. Thanks to its high axial resolution, that is the ability to differentiate image points that are situated behind each other, it can also manage highly complex structures. Reflective, refractive, shiny or transparent, surfaces such as lenses are no problem for the Precitec LR, adds Hexagon.
The technical principle of the sensor is based on chromatic confocal measurement. In this process white light is directed towards the surface to be measured in a wavelength-dependent manner. A spectrometer analyses the reflected light and determines the distance between the sensor and the measured object.
The Leitz Infinity is equipped with the high precision tactile high speed scanning LSP-S4 measuring head as standard. In combination with the non-contact Precitec LR, users can switch automatically between tactile and vision metrology within one measuring process.
