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'. Cewei has established the concept of "we design, we manufacture", and now it has elevated this concept to the enterprise development goal of "highlighting the high-end optical technology feeling in the mirror industry". Starting from 2008, we have been collaborating on technology development with Japan's Varuda Optoelectronics Co., Ltd. and Opter Optoelectronics Co., Ltd. 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.
