LIP Exposed Linear Scale

LIP

LIP linear encoders from HEIDENHAIN are available in accuracy grades from ± 1 µm to ± 0.1 µm. 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 4 µm produces an output signal period of 2 µm. This results in a measuring step of only 0.5 µm even without interpolation.

The high uniformity of the scanning signals permits measuring steps as fine as one nanometer.
