China & South Optical Crystal (CSOC) is the first manufacturer of optical glass products in Hong Kong.
It was in 1972 when CSOC was established and became a milestone in the history of optical production in Hong Kong. CSOC was the first factory that engaged in the production of watch glasses in Hong Kong, whilst gradually improving and extending to all fields, turning into a professional manufacturer of optical glass products. Through continuous exploration and development, CSOC expanded out of Hong Kong and established a number of new companies in Shenzhen and the Jiangsu province. CSOC has developed now into becoming a comprehensive manufacturer specializing in the production of optical sapphire windows and optical glasses through a step by step process.
