Product Description
Advanced Optical Measuring System
Features:
1. The slide carrier of the scales, use a five bearing design and six spring for optical grating linear transducer
2. Can connect a positive press system to reach waterproof IP65.
3. Moving speed can more than 120m/min.
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 for the accuracy measurement report of the factory inspection, ensure all the linear scale match our accuracy grade.
