LIP 372

Description

The HEIDENHAIN LIP 372 series is available in accuracy grades from ± 1µm to ± 0.1µm. Through the choice of scale material it is possible to use a measuring standard whose thermal behavior is comparable to that of the measured objects. A grating period of 4µm produces an output signal period of 2µm. This results in a measuring step of only 0.5µm even without interpolation. The high uniformity of the scanning signals permits measuring steps as fine as one nanometer.
