A lens is made by grinding a transparent material such as glass into a circular sheet so that both surfaces are curved or one side

One side of the meniscus lens is convex and one side is concave. It can be a convergent lens or a divergent lens, which is

The double concave lens is similar to the flat concave lens. The focal length is negative, but the light incident in parallel diverges outward. The

The biconvex lens is a biconvex lens sheet, which comprises an incident surface and an emitting surface. It is characterized in that the focal length

They have a negative focal length and are used to diverge a beam of parallel light. A flat concave lens has a spherical surface on

The focal length of a single lens is the distance from the main point to the focus. The design wavelength of the lens is 546.1
