HEIDENHAIN length of the meter is a measurement tool, the measurement of HEIDENHAIN length gauges wide range of applications, and scientific testing methods, tools emerging, advanced technology products is even more far than the previous measurement tools are good old-fashioned a lot of great precision, the more efficient nature of many of the problems found. 
 HEIDENHAIN incremental grating optical scanning method for scanning, so no mechanical contact and no wear. By special arrangement of light passing through the scanning reticle and the optical grating in the pool after irradiation. Light cycle the battery a small sinusoidal signal output. Follow-up to electronic equipment of the output signal down to a very small nano-scale measuring step. With optical scanning principle, a very fine grating engraved engraved lines and clean edges to ensure a high quality line output signal, a signal cycle to ensure that small position error. This is particularly reflected in the use of DIA DUR phase grating scale for measuring the length of terms of HEIDENHAIN. Scan method using interference can occur only 2um sinusoidal incremental signals 
 HEIDENHAIN length gauges have measuring range, high precision and accuracy characteristics of chaos. Based on its technology is based on optical scanning grating measuring incremental principle. 
 HEIDENHAIN measuring the length of the meter base with odds and ends, that is glass or glass ceramic substrate incremental encoder. These benchmarks measure support for a large measuring range, is not sensitive to vibration and shock, and has determined temperature. Accuracy from the baseline measure atmospheric pressure and relative humidity change - this is total length of HEIDENHAIN a prerequisite to the premise of the temporary chaos. 
 Grating it with the template developed by the Heidenhain's carved its own line of machine manufacturing. Manufacturing process, strict temperature control of chaos to ensure the entire grating length measurement precision. Developed by HEIDENHAIN's own copy of the DIA DUR process will be the template for the grating substrate grating, grating it with the template developed by the Heidenhain's carved its own line of machine manufacturing. Manufacturing process, strict temperature control of chaos to ensure the entire grating length measurement precision. Developed by HEIDENHAIN's own copy of the DIA DUR process will be used for grating grating template matrix, the output is very durable and ultra-thin chrome grating.
