Jilin Tianhua Opto-electrical Technology Development Co., Ltd., production and sale of precise optical elements. Our company locates in Changchun City, Jilin Province, the optical base of China. We specialize in cylindrical mirror.
There are more than 60 people in the company, who are researchers and professional technicians of Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences. Our company has advanced optical cold-working detecting equipments and process equipments, and provides high-quality products and professional services for customers. We can produce cylindrical mirrors of different specifications, sizes, radii, materials and special shapes or organized types. We can process high-precision cylindrical mirrors of special optical characters, such as: achromatic cylindrical mirror, parabolic mirror, cylindrical ellipsoidal mirror and hyperbolic mirror. Cylindrical mirrors of complicated shapes, such as: fan-typed, off-axis cylindrical mirror, angular cylindrical mirror, etc. In addition, we produce other optical elements such as flat mirror, window, prism, spherical lens, etc. Our company can design and process all kinds of optical elements according to requirements, and do gluing and filming on products. Substrate materials we usually use are optical glass, BK7, K9, violet quartz, ultrared quartz, CAF2 crystal ZF soft material, etc. (Special material should be supplied by customers)
The company takes "be faithful and honest, keep quality first, supply products on time and pursue perfect" as its operational principle. We are glad to communicate and cooperate widely with friends in domestic and abroad.
We promise: to become your "wholesaler" of optical elements with high quality, high speed and low price.

Changchun Juncheng Optical Instrument Co., ltd. is located in the optical base in China -- 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. Juncheng will set "efficient innovation, honest and trustworthy, customer first, quality first" as principle, and strive to become a leader in field of optics.
Sincerely look forward to cooperating with you!
