Product Description
Advanced Optical Measuring System
The slide carrier of the VS / VA series scales, use a five bearing design and six spring for optical grating linear transducer, specially in long dimension scale like the large Lathe machine. The Accuracy is better than the GS20 series long scale.
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 glass grating transducers are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
Accuracy report in QR code
Each linear scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
