Cylindrical Lenses Types of Cylindrical Lenses. A cylindrical lens is characterized by both its focal length and its geometry. They can be square, circular, or rectangular. A plano concave cylindrical lens will expand light on a single axis. It is also known as a negative cylindrical lens, and is used for one-dimensional image compression, anamorphic beam shaping, and laser line generation. A plano convex cylindrical lens focuses light on one axis, and can also be used to magnify an image in one direction... (read more)Browse Optical Lenses Datasheets for Avantier Inc. -
