Problems solved by technology

[0002] As the demand for high-index optical systems continues to increase, some novel optical structures have also been developed to a certain extent, especially the continuous emergence of folded optical systems including transflective, but in any case, high-index folded optics system, its pursuit of improving the user experience of end customers is never-ending, and for the semi-transparent and semi-reflective optical components on the existing market, it is characterized by good reflection and transmission effects on the reflective side, but It is also inevitable that there is a significant reflection effect on the side of the transmission surface, which brings a lot of stray light to the optical system containing reflection and transmission optical components, greatly affecting the effect of the optical system
