Lens with novel structure and lens group

A lens with a novel structure and a lens group comprise a substrate layer and an optical structure layer, and the surface of the substrate layer is coated with a film, so that the lens not only has the function of changing the optical propagation direction, but also has the function of infrared cut-off filtering. 一种新型结构透镜和一种镜头组，包括：基底层和光学结构层，通过在基底层表面镀膜，实现透镜不仅具有改变光学传播方向的功能，还具有红外截止滤光的功能。
