Heidenhain EXPOSED LINEAR SCALES

The measuring standard for linear encoders of the LIP and LIF design types is a phase grating applied to a carrier of steel (LIP) or glass (LIP and LIF).

Linear encoders of the LIDA type operates with AURODUR steel scales with a graduation of highly reflective gold lines and matte etched spaces.

Linear encoders of the LIM type operates according to a magnetic scanning principle.

The PP two-coordinate encoder has a two-dimensional phase-grating structure on a glass substrate. Through an interferential scanning method such as is used on the LIP and LIF linear encoders, this structure enables the PP to make measurements in a plane.
