Supplier Information
Harbin Jinyang Optoelectronics Technology Co., Ltd. is a high-tech private enterprise integrating optics, mechanics and electronics. It has domestic advanced CNC surface milling machines, high-speed polishing machines and multiple imported testing instruments, ZS-1100 coating machine and American MDC-360C automatic control system, and a group of experienced senior optical engineers and technicians. The company's main products include: quartz hemispherical resonators, quartz bases, aspherical cylindrical mirrors, precision optical cold reflectors (bowls), parallel light reflectors for searchlights, ellipsoidal reflectors for follow spotlights, special reflector groups for digital cinema projectors, optical glass for cinema projection windows, light guide columns, anti-reflection glass, precision optical element cold processing, and can process sapphire, silicon boride, quartz, K9 and other materials of optical elements.
The company's person in charge Liu Hongqing has been engaged in optical technology for 40 years. He has directly participated in the design and manufacture of off-axis reflectors for national film projectors, the development of reflector bowls for national bullet train headlights, and in 2004, as the production dispatcher of the optical branch of the film machine factory, directly participated in the manufacture of head-up display systems and simulated sights for a simulation institute.
After years of unremitting efforts, our company has made major breakthroughs in the production and processing technology of quartz hemispherical resonators. The indicators such as coaxiality, concentricity, and roundness are all within 1μm, and the Q value is above 15 million. After polishing, the components are pickled, and there are no microcracks on the surface or return to the sand surface. Our company has also made its own efforts for the localization of digital cinema projector accessories. Due to the high temperature in the working state of the film projector, the accessories of the optical path part often need to be replaced. The materials of the optical path part are mostly JGS1 quartz or high borosilicate as raw materials or substrates, such as uniform light square rods, lens groups and reflector groups, etc. After analyzing a large amount of data, our company, with excellent processing capacity and years of processing experience, has been recognized by the market and perfectly solved the problem of expensive original accessories. At present, the market share of domestic accessories in the domestic cinema industry has reached more than 70%.
