Dimensional Metrology

With many years of experience with measurement methods development in a wide spectrum of applications.

Meopta has extensive experience in dimensional measuring and to ensure quality measurements for our customers we have several laboratories with controlled environments. We are able to measure most of the length parameters including shape and surface deviation.

We use standard measuring devices (calipers, micrometers, thread gauges, etc.) and also several hi-tech microscopes and 3D measuring machines (CMM – Coordinate Measuring Machines).

Our CMMs from Carl Zeiss have a rotary head with scanning sensor. Measuring range of our biggest machine is 1000 x 1600 x 600 mm with the accuracy of E_{0,MPE =}1,9 + L/300 (μm). Usage of CAD models makes the measuring process programming very fast. Our measuring software includes the module for 2D and 3D curves evaluation.
