Description
Cylindrical lens is used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.They are available in either plano concave or plano convex configurations. Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.
What is a cylindrical lens?
The cylindrical lens can change the size of light due to its elongated shape. What makes cylindrical lenses different is that their surfaces are cylindrical.
Since only one axis has a spherical radius, light converges, amplifies, or expands in only one direction. Since the light is concentrated in one dimension, the image is stretched.
The cylindrical lens can be a plano convex lens or a plano concave lens, the former will focus the beam, and the latter will expand the beam. According to your needs, you can choose the cylindrical lens suitable for your application needs.
