LIP linear encoders from HEIDENHAIN are available in accuracy grades from ▒ 1 Ám to ▒ 0.1 Ám. 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 Ám produces an output signal period of 2 Ám. This results in a measuring step of only 0.5 Ám even without interpolation.
The high uniformity of the scanning signals permits measuring steps as fine as one nanometer.
