It is a part of a cylinder and can replace a sphere. The cylindrical lens can turn point light into line light and can be used as a linear laser generator to generate laser. The lens is magnified at the same size, so it can stretch the image, so it can focus the light into a slit or focus it into a linear scanning detector. Due to strict tolerances on tilt and wedge, high quality imaging lenses will produce straight or better images than standard cylindrical lenses.

Example with BK7 material：These N-BK7 Plano convex cylindrical lens are available uncoated or with one of five antireflection coatings (-A, -AB, -B, -C, or -D), which reduces the amount of light reflected from each surface of the lens (see the Selection Guide table below for coating option). Since approximately 4% of the incident light is reflected at each surface of an uncoated substrate, the application of an AR coating improves transmission, which is important in low-light applications, and prevents the undesirable effects (e.g., ghost images) associated with multiple reflections. Having optics that are AR coated on both surfaces is particularly desirable for applications utilizing multiple optical elements. Please see the Graphs tab for additional coating information.
