Product Description
Advanced Optical Measuring System
The slide carrier of the VS / VA series scales, using 5 bearing design and 6 spring for optical grating linear transducer, make sure the VA scales not effected by installation, the spring can adjust the angle when the operator install not good for the alignment.
The reader head still in the best way fir on the grating glass, the accuracy of VA scale is totally different with the GS or other brand in China mainland.
VA scale has a small PCB inside the 9 PIN connector, the laser compensation data is store inside, with our LCD Digital display unit, the compensation data will directly load the ECF file (compensation file) into the DRO, accuracy up to ±2μm.
Aging Test

Easson Optical Linear Scale's reader head need to power on for 72 hours aging test before assemble,
make sure all linear scale's quality is reliable.
100% Laser calibration

All linear encoder glass scale are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
