Optical elements are the basic components of optical systems, also known as optical components, which can often play the role of imaging, such as lenses, prisms, mirrors, etc. Any instrument, device, or thing used to form an optical path, compose optics, or related to optics is an optical element. For example, a concave lens has a divergence effect on light. The incident light passes through the focus and refracts through the concave lens, and the refracted light is parallel to the main axis. A convex lens has a convergence effect on light. The incident light passes through the focus, and the refracted light is parallel to the main axis after being refracted by the convex lens. Read More
