Application Cases
TESA-SCAN
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 130 mm in diameter, which can be as long as 1000 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.
