Shanghai, known as the cradle of China's optical industry, has established its position in the domestic optical industry through half a century of glorious history. Guangguang, a story that can be traced back to military enterprises before liberation, was once known as the "Eastern Zeiss" in the 1960s. Dimensity Optoelectronics originated from light and was nurtured in the 'cradle'. At the end of the last century, the reform of Shanghai's optical industry benefited from the market brought by the American LWS optoelectronics injection, and the company established the concept of "we design, we manufacture". Now, Cewei has elevated this concept to the development goal of "highlighting the meticulous feeling of optical technology in the mirror industry". In 2008, we began collaborating on technology development with Japan's Varuda Optoelectronics Co., Ltd. and Opter Optoelectronics Co., Ltd., and hired a software PhD from Waseda University to set up a workstation in the company. The introduction of these technologies marks the era when the term "optoelectronics" truly combines the intelligence of human eyes and brains. It is an important process for China's industrial status to catch up with imported products, and this symbol and process are the exploration and pursuit of measurement and maintenance personnel!

The company's main products include biological microscopes, stereomicroscopes, metallographic microscopes, polarizing microscopes, fluorescence microscopes, phase contrast microscopes, tool microscopes, measuring microscopes, metallographic equipment, hardness testers, centrifuges, refractometers, etc.
