VS20 Glass Scale Dro Optical Measuring Glass Scale Linear Encoder

High Accuracy Long Distance Linear Encoder Scale For Large Milling Lathe Boring Machine

​Advanced Optical Measuring System

1. Advanced six-spring & push-pull structure to ensure repeatability less than 2 micron；

2. Advanced 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 power on for 72 hours aging test before assemble,the aging test exposes defects in the process, design, materials and other aspects of electronic devices before they leave the factory. Therefore, it is of great significance for companies to modify product designs in time, so that products can be sold after they are aging and stable.

Connector interface

DSUB 9PIN

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.

Easson was established since 1995.It is a high-tech enterprise specializing in design and manufacturing of precision measuring equipment, obtained more than 20 national invention and utility model patents. Our product field in DRO systems, precision optical profile projectors, video measuring machine and etc..

Easson's factory building is specifically design and built for the manufacturing of precision measuring equipment, has four Laser interferometers for being the company's length measurement standard and R&D.

Easson is one of the few companies in the industry that has its own high-precision grating master which use own fully-developed grating master lithography equipment, produce the absolute linear encoder and high accuracy CNC linear encoder.

Our quality management system has been assessed and registered by National Quality Assurance Ltd.(NQA) against the provision of ISO 9001:2015.

Strong Technical Capabilities And Scientific Research Resources

Over the years, the company has established a very close and effective cooperative relationship with scientific research institutions such as Xi'an Jiaotong University and Jilin University, taking advantage of the abundant talents and theoretical advantages of university scientific research institutions, combined with the company's long-term accumulated technology and practical experience in this industry , so that we have created many products that are leading the domestic industry.

In addition, the company actively participates in the scientific research and industrialization projects issued by the state and Zhuhai City.

For example, in 2011, the company participated in the "High-end CNC Machine Tools and Basic Equipment" led by Xi'an Jiaotong University and issued by the Ministry of Industry and Information Technology of China "Science and Technology Major Project. And combined with Tianjin University, Hefei University of Technology, Chinese Academy of Metrology... and other units jointly developed.

The company's AS-40 series grating ruler is one of the results of this project, which is industrialized by our company. And our company's EC-2 Pseudo-random absolute coding is one of the project achievements jointly developed by our company and Jilin University.
