TESA-SCAN OPTO- ELECTRONIC MEASURING CENTRES

FAST ROUND PART INSPECTION

The whole TESA-Scan product line belongs to the range of dedicated non-contact opto-electronic measuring centres that provide Users with a complete solution for inspecting small round parts quickly.

Including a variety of systems such as those usually integrated into profile projectors or microscopes, they offer the round part manufacturer a more capable alternative to traditional inspection methods.

TESA’s product range can measure shapes and sizes of round parts from 0,3 up to 80 mm in diameter, which can be as long as 500 mm

Operating Principle:

All TESA measuring centres incorporates high-resolution CCD linear sensors. Each sensor is subdivided into thousands of light sensitive pixels. As the part image is being projected, these sensors,which act as light sensitive rulers, can detect the slightest changes at sub-pixel level.

The workpiece is illuminated with parallel white light and its image is projected onto the linear CCD sensors, which are inclined to 7,5°. They provide the information obtained from the image,thus allowing accurate analysis of the geometry of the workpiece features

Complex part features such as straightness or circularity can easily be inspected by combining rotation with axial movement. This permits any surface of the workpiece to be scanned dynamically in order to determine the part axis for true 3D alignment and reference purposes.
