Product Description
Advanced Optical Measuring System Features


Aging Test

Easson Optical Linear encoder's reader head need to power on for 24 x 3 hours aging test before assemble,
make sure all linear encoder's sensor is reliable for long time.
100% Laser calibration

All linear encoders 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 encoder is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
