| The circular graduations of rotary
encoders are manufactured with the DIADUR process developed by
HEIDENHAIN. It produces a radial grating of opaque chromium lines with
very high edge definition. This high edge definition is a precondition
for a high quality of scanning signal. The glass substrate permits the rotary encoders to operate at high temperatures — as high as 100 °C (212 °F) on some models — without any significant reduction of signal quality. DIADUR circular graduations form the basis for the accuracy of HEIDENHAIN rotary encoders. |
