Bore hole depth

It is essential to measure in bore holes for some applications. In doing so, the depth or the wall structure of a bore hole can usually be measured. Only confocal axial or radial miniature sensors with 4 mm external diameter are suitable for this. Triangulation sensors would not provide any measurement results due to the shadowing of the laser in bore holes.
