Historical evolution

Yuheng optics is the most powerful professional manufacturer of grating sensor and optical instrument industry in China. Yuheng Times is a wholly owned subsidiary of Yuheng Optics.

In 1965, changchun No. 1 Optical instrument Factory (predecessor of Yuheng optics) was established and the first optical instrument was born.

In 1967, China's first industrial grating encoder was born in Yuheng Optics;

In 1980, 1984 and 1992, the grating encoders produced by Yuheng Optics (formerly Changchun Yiguang) were used for launch of Carrier rockets and communication satellites in China, and were awarded by the CPC Central Committee, the State Council and the CENTRAL Military Commission.

In 1994, it was established as the only national encoder engineering pilot base in the industry; The first one in the industry to obtain the license of self-management import and export right of the Ministry of Foreign Trade;

In 2002, it was approved to establish the National postdoctoral Research station.

In 2004, ERP enterprise resource planning system was implemented and information management was implemented successfully.

In 2005, the grating Encoder project was approved by the National Special project to revitalize the high-tech industry development of the old industrial base in Northeast China.

In 2006, Changchun Yuheng Times Optoelectronic Technology Co., LTD, a wholly-owned subsidiary of Yuheng optics, was established, focusing on the continuous development of Yuheng's traditional optical instrument products.

In 2007, "Yuheng" raster encoder won the Chinese famous brand;

In 2008, jilin province was one of the first batch of national high-tech enterprises to pass the re-evaluation, and the new industrial science and technology park of 30,000 m2 was completed in the same year.

In 2009, the project of "High Precision Synchronous Control of Photoelectric Encoder Industrialization" was approved by the National Information industry revitalization and technical transformation special project.

In 2010, I was in charge of the formulation of grating Angle Encoder (JB/T 9942-2012) and industry standard of Grating Rotary Encoder (JB/T 11498-2013). Participate in the development of the "CPE-BUS Displacement Encoder Bidirectional serial communication Protocol Specification" industry standard; Jointly undertake the national public welfare industry research project "Grating Encoder Technical Standard Research" in 2010 with Jilin Provincial Standard Research Institute;

In 2012, "Yuheng" was identified as China's well-known trademark by the State Administration for Industry and Commerce.

In 2012, "Development of High Precision and High Resolution Absolute Grating Rotary Encoder" was approved by the National "12th Five-Year plan" major science and technology project.

In 2013, Yuheng Optotech Co.,Ltd was acquired by Changchun Institute of Optics, Precision Machinery and Physics of Chinese Academy of Sciences. Yuheng Era was merged into Changguang Industrial Group.

In 2013, the Research and Development and Industrialization of Highly Integrated Single-code Absolute Grating Ruler was approved as a national key science and technology special project during the 12th Five-Year Plan period.

In 2014, won the honorary title of "Grade A Taxpayer of Jilin Province in 2014";

In 2015, won the honorary title of "Project Model Unit for Technical Standard Improvement in Jilin Province";

In 2016, "Development of High Precision and High Resolution Absolute Grating Rotary Encoder", a major national science and technology project of the 12th Five-Year Plan, passed the technical acceptance smoothly.

In 2017, "Development and Industrialization of High-resolution Angular Displacement Sensor" was approved as a key project of national major scientific instrument and equipment development.

In 2017, An agreement was signed between Yuheng Times and Northeast Normal University, in the School of Physics of Northeast Normal University, to jointly build the "Off-campus Practice Education Base of NORTHEAST Normal University". The education base mainly serves the three majors of Electronic information science and Technology, electrical Engineering and its automation and physics, college of Physics, Northeast Normal University, in order to actively explore the mode of school-enterprise joint training innovative talents. To realize resource sharing, and to realize more extensive cooperation between enterprises and NORTHEAST Normal University in employment and recruitment, product research and development, achievement transfer, technical training and other aspects.
