Grating measurement principle and measurement standard
The measuring standard of grating ruler is glass grating, the glass grating is on the glass with very precise periodic lines. The final measurement accuracy of the grating ruler is determined by a series of quality indicators such as the dimensional accuracy of the periodic grating lines on the grating glass, averageness and transmittance contrast...
Based on the feasibility of cost and economy, the grating glass in the grating scales sold on the market is produced by copying a set of master gratings through a photolithography process. The measurement accuracy of the grating scale(ruler) is completely determined by the accuracy and quality of the master and the perfection of the lithography process.
Easson is one of the few domestic companies that have the ability to produce grating masters on their own. The grating masters used in the production process of grating rulers are completely produced by our company.
100% Laser calibration
All glass grating transducers are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
Each linear scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
