The scale of optical glass industry continues to expand, and the market concentration will gradually increase

　　Optical glass refers to the glass that can change the light propagation direction and the relative spectral distribution of ultraviolet,visible and infrared light.Optical glass can be used to make lenses,prisms,mirrors and glass in optical instruments.It is a key component of optical instruments.With the rapid development of global camera,smart phone,security monitoring,car mirror,AR/VR,UAV and other industries,the downstream demand for optical glass continues to grow.

　　Digital cameras and cameras in traditional optical industries such as optical glass and downstream application market share continue to shrink,the smartphone market is increasingly saturated,and the growth rate of demand slows down.However,the demand for optical glass in these three fields,especially in the field of smart phones,is still huge.Emerging industries such as security monitoring,vehicle mounted lens,AV/VR,motion DV,UAV and home projector have developed faster and become a new driving force for the growth of optical glass market.In general,the optical glass industry has broad prospects for development
