Product Description
Advanced Optical Measuring System Features
- Using advanced six-spring & push-pull structure to ensure repeatability less than 2 micron；
- Using engineering mechanics analysis and design to ensure that the dynamic speed more than 120 m/min
Aging Test
Easson Optical Linear Scale's reader head need to aging test for 3 days before assemble, make sure all linear scale's electronic devices and quality is reliable.
100% Laser calibration
Easson each linear encoder are undergone rigorous calibrated by our in-house laser interferometer, and can provide accuracy test reports to ensure product quality and quality traceability.
Accuracy report in QR code
Each linear encoder is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
