Chinama Trading Company is a subsidiary of China Optoelectronics Technology Group, mainly responsible for the foreign trade sales of products from various industrial factories of the group. It is a typical integrated trade company of industry and trade. China Optoelectronics Technology Group has inherited over 20 years of Chinese military technology and is a research and development oriented industrial cluster. It is one of the few enterprises in China that has mastered the entire process of laser holographic diffraction grating preparation from the early stage of photolithography to the subsequent stage. The holographic diffractive optical elements and holographic optical waveguides developed and manufactured can be widely used in aerospace, flight aiming helmets, infantry aiming helmets, individual rapid aiming devices, benchmark measurement, medical equipment, spectrometers, intelligent electronic products, 3D printers, 3D scanners, network and information security technologies (hardware and software) and systems, the Internet of Things, electronic specialized equipment and instruments, advanced perception and reconnaissance detection, blockchain technology, virtual augmented reality technology, simulation technology, spatiotemporal benchmark technology and equipment, covering military tactical equipment supplies, as well as civilian AR, VR, automobiles, daily necessities, art, consumer goods and other categories of goods. Especially in recent years, the AR augmented reality core hardware developed and manufactured by the group has a wide range of market application scenarios – holographic waveguide gratings, AR retinal projection lens gratings, and other comprehensive performance advantages. Some technical indicators even exceed Eotech holographic technology in the United States, truly achieving the world’s second and China’s first!
