Description

      Shanghai Yidian Physical Optical Instrument Co., Ltd. (abbreviation: Shanghai Yidian Material Light) is the key backbone enterprise of the joint-stock system of “Shanghai Instrument and Electronics Instrument” and the birthplace of the first polarimeter in China. Its predecessor is “Shanghai Jingke”, which has a history of more than 60 years. It has passed ISO9001 quality management system certification and ISO14001 environmental management system certification in the industry. It has been rated as Shanghai High-tech Enterprise for 30 consecutive years.
      Founded in 1951, the company is currently the most famous professional physical optics instrument system integration supplier and manufacturing base integrating R&D, manufacturing, application services and overall solutions. Its registered trademarks “Yidian Wuguang”, “SGW” and “Shenguang” have a long history and have become well-known brands in China. For more than 60 years, the company has always focused on the development of new products, and accumulated a wealth of experience, always keeping pace with international new technology, high-tech throughout the product development design, and independently developed and manufactured the first multi-wavelength in China. The automatic high-speed polarimeter, the first automatic constant temperature Abbe refractometer, the first visual automatic two-purpose melting point instrument and the image processing melting point instrument and many other high-end products have always led the development trend of the domestic industry and become the industry benchmark. .
      The company now has 10 series of more than 100 kinds of professional physical optical instruments such as polarimeter, melting point meter, refractometer, haze meter, colorimeter, laser particle size analyzer, turbidity meter and stress meter. In the pharmaceutical, drug testing, colleges, sugar, quality inspection, food, chemical, measurement, light industry, textile, building materials and other industries enjoy high recognition, market share is among the best. Products are also exported to Southeast Asia, the Middle East, Europe and the United States and other regions.
      “Shanghai Yidian Material Light” will further follow the market demand and continue to adhere to the business philosophy of “fast, flexible, effective, consistent and shared”, using the latest technology, development and innovation, as always, to provide quality products and services to customers.
