With this 3D camera system „3D RIG“, the focus was on ease of movement and maintenance freedom. Metallic ball bearings cannot be used because of their weight, and they would also be prone to corrosion and require lubrication. DryLin® SLW cross tables and DryLin® W linear guides ensure that both cameras can be adjusted exactly the same. This is important since it is the only way the threedimensional image can be produced.
