| Cylindrical lenses (also called astigmatic lenses) have at least one surface that is formed like a portion of a cylinder. They are used in rangefinders to produce astigmatism, or the stretching of a point of light into a line. Plano-convex cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications. These cylindrical lenses measure 4" long x 1/8" wide x 1/16" deep, with polished concave top and flat base surfaces, and ground ends. The edges along the length may have some slight roughness due to their thinness. Focal length is 3mm. A great find for the optics hobbyist or experimenter! |
