According to Lin Enping, Chairman of Daliguang, plastic prisms have passed customer testing and it is still uncertain whether they will be imported. It is believed that the customer mentioned by Lin Enping may be Apple. According to market analysts, the biggest selling point of the iPhone 15 last year was that it was the first time the Pro flagship was equipped with a periscope lens, exclusively supplied by Daliguang. In addition, the prism was also one of the newly added key components, with each periscope lens equipped with two glass prisms, supplied by Crystal Optoelectronics.
