High precision of gratings whose linear thermal expansion is suitable for the application required. Measuring lengths up to 30 m, accuracy grade up to ± 1 µm and resolutions up to 0.1 µm. Certificate of metrological inspection supplied with each scale.
Optical scales are manufactured in compliance with strict quality standards and they are produced in seven different models. The product documentation, which can be supplied on request, underlines the high quality and reliability of products.

With absolute scale you obtain measure of length in “absolute” units.
With incremental scales, you get as result only the “difference” of measures of the length! Therefore you need for the incremental measuring a point of reference!
