Test items are converted into digital volumes using computer tomography. Two X-ray tubes of the v|tome|x m (300 kV microfocus tube and 180 kV nanofocus tube) are combined with a digital 4,000 x 4,000 pixel detector to cover a very broad spectrum of tests with high magnification and performance. These range from high-resolution CT scans (down to < 0.5 μm) of low absorbing samples to the inspection of cylinder pistons. The maximum sample size is 500 mm dia. x 600 mm height and the 3D scan volume is max. 420 mm dia. x 400 mm height with weights of up to 50 kg. The metrology version achieves a measuring accuracy of up to 4 + L / 100 μm in compliance with VDI 2630.
