Description:
A plane concave lens has a concave side and a plane-side with a negative focal length. Usually used to collimate a beam, increase (decrease) the focal length, or enlarge (decrease) the image. In order to get less spherical aberration, when it is a collimation beam, that should be incident on the concave side of the plane concave lens.
