Product Description
Advanced Optical Measuring System
VS
The difference between VS series and the currect China market's optical glass scale is the slide carrier of the VS series optical linear scales, using a five bearing design and six spring for optical grating linear transducer, more reliable support bracket system, specially in long dimension scale like the long Lathe machine. The Accuracy is better than the GS20 series long scale.
100% Laser calibration
All Easson glass grating transducers are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
Accuracy Measurement Report
Each linear scale is printed with a QR code, which is convenient for customer to view the accuracy measurement report of the factory inspection.
