Ultra-large-angle anti-reflection lens

The invention relates to an ultra-large-angle anti-reflection lens, which comprises an incident lens, an emergent lens and an anti-reflection film layer arranged between the incident lens and the emergent lens, wherein the refractive index of the incident lens is smaller than that of the emergent lens. Compared with the prior art, the ultra-large-angle anti-reflection lens disclosed by the invention has the beneficial effects that the reflectivity is less than 1% in a visible spectrum range (400-700 nm) and in a range of an incident angle of 0-80 degrees. 本发明涉及一种超大角度减反镜片，包括入射镜片、出射镜片及设于两者之间的减反射膜层，所述的入射镜片的折射率小于出射镜片的折射率。较之前的现有技术，本发明具有以下有益效果：本发明该减反镜片能实现可见光谱范围(400-700nm)内，在入射角为0-80°的范围内都能实现反射率小于1％。
