Double concave lens consists of two concave spherical surfaces with a negative focal length, which is used to make the beam diverge, and is often used in beam expansion, collimation, projection, and focal length expansion of optical systems applications. They are usually used in conjunction with other lenses to improve imaging performance by reducing chromatic and other aberrations.
