Our solutions
MABRI.VISION specializes in the development and implementation of complete vision solutions for use in production and research. Whether 100% testing directly on the product carrier system or in the clean room: by combining different high-performance optics, we meet your individual testing requirements.
How do we check?
The testing procedures can be combined in modular ways and are based on the properties and characteristics to be tested for your component. Depending on the requirements and component size, it is also possible to vary the size of the sensors.
Shadow casting system
When testing components using the shadow casting principle, the contours of the test parts are recorded with high accuracy. This makes it possible to measure difficult features such as contact pins and pins, which are often challenging for other 3D inspection methods. By adding this test unit, a high level of flexibility is achieved in the detection of difficult test features, even with short cycle times. However, this testing technology not only impresses with its precision, but also with its high measurement rate, even for complex testing tasks. Shadow testing is therefore ideal for testing moving products directly in the production line.
particularities
Shadow testing is characterized by measuring high aspect ratio features such as contact pins and pins. The results are robust and precise measurements, as well as a high level of flexibility, which is made possible by the combination of linear technology and a rotation unit.

Telecentric 2D inspection
The precise inspection of large components using 2D camera technology is challenging. This is due, on the one hand, to the lack of 3D information and, on the other hand, to the requirements for the camera and optics. We address these challenges by using special telecentric lenses with a large field of view. In addition, we rely on the latest camera technologies and thus achieve new possibilities in precision and resolution. In addition, we use the 3D information from the remaining test stations to further optimize the alignment of the measuring plane.
3D line sensor
Line sensors are an effective and cost-effective solution for inspecting 3D features and complete component digitization. What is particularly noteworthy is the speed and precision of the surface measurement. By using the latest light section sensors, highly accurate measurements are also possible for multi-layered, reflective and transparent materials.
Thanks to their high measuring speed with up to 6 million measuring points per second, 3D line sensors are ideal for use in inline testing systems. The robust sensors easily withstand the specific requirements of industrial high-efficiency environments. Rely on both non-contact and seamless testing in your production with fast, three-dimensional detection of large surfaces.
particularities
With up to 6 million data points per second, the 3D line sensor is one of the most commonly used sensors in industrial inline use. Robust measurements with resolutions in the single-digit micrometer range correspond to the industry standard. The 3D line sensor can be used flexibly on different surfaces.
