Changchun Juncheng Optical Instrument Co., ltd. is located in China's optical capital -- Changchun city of Jilin province. The predecessor of our company Juncheng optical glass processing factory was founded in 2005. With the help of changchun unique optical scientific research and processing environment, Juncheng optics developed rapidly. Now we have become a collection of optical product design, R&D, processing and marketing, and as one of the sophisticated leader in this field. In 2015, we officially changed the name to Changchun Juncheng Optical Instrument Co., ltd. After more than ten years of development, there are eight people in our scientific research team. All of them come from Chinese academy of sciences, changchun institute of precision machinery and physics. The company also hired a senior technical consultant to provide technical guidance throughout the year. Over the years, the company acquires continuous innovation in the field of precision optical components manufacture, and takes part in China Aerospace and military products R&D and production many times. At present, the company has passed ISO9001:2008 quality system certification. Our main products are spherical lenses, cylindrical lenses, prism, optical window, reflector, filter lens and achromatic lens etc. In addition to the common optical glass, we also can process CaF2, MgF2, BaF2, Se, ZnS, Ge, Si, sapphire and other crystal. For coating, we can do from 0.2um-20um, including AR coating, high reflect film, half reflect film, the splitting film, laser crystal film, IR film, UV film and optical fiber film etc. Especially in the laser, the frequency doubling crystal, IR crystal, and UV band coating we have huge advantage. We not only have more than 50 advanced milling grinding, polishing, plating equipments from the United States and Japan, and also introduced the ZYGO horizontal laser interferometer, AK100 horizontal laser interferometer, LAMBDA950 spectrophotometer, the focal length meter and other test equipments. We ensure product quality by advanced production technology and strict inspection. We believe product quality is the life of enterprise, and provide our customers with the best quality and service, to seek long-term development of the enterprise.With the expansion of foreign trade, in recent years, the company's products are not only widely applied in domestic aerospace, military industry, medical treatment, laser, communication and other industries, and also gain customer recognition and favor from Europe, America, Japan, South Korea, Singapore and other countries of the overseas.
