Features of biconconcave lens:
Both sides of a biconconcave lens are concave and have the same radius of curvature. A biconconcave lens is with negative focal length, usually used for beam collimation, increasing (decreasing) focal length, or enlarging (decreasing) an image. Biconconcave lens is often used for imaging or beam collimation, and the coated lens is also widely used in visible light and near infrared applications.
