Cylindrical lenses are utilized for astigmatism correction in the eye and rangefinders, inducing astigmatism by elongating a point of light into a line. They find extensive application in barcode scanning, projection optics systems, laser measurement systems, and holography. OST Photonics offers cylindrical lenses in plano-concave or plano-convex configurations.

What Is a Cylindrical Lens Used For?
Cylindrical lenses are specialized optical components used primarily to correct astigmatism, a common refractive error in the eye. Unlike spherical lenses, which have the same curvature in all directions, cylindrical lenses have curvature in only one direction. This unique property allows them to focus light into a line rather than a point, making them ideal for applications requiring precise control over light direction and focus. OST Photonics, a leader in cylindrical optics, offers high-quality cylindrical lenses designed to meet various optical needs.

In the field of optometry, cylindrical lenses are crucial for subjective refraction tests. A cross cylinder, which combines two cylindrical lenses with equal strength but opposite power, is often used to diagnose astigmatism. This tool helps in assessing both the strength and axis of the astigmatic power, ensuring accurate prescriptions for corrective eyewear. Beyond medical applications, cylindrical lens optics are also employed in laser systems, imaging, and optical data storage, showcasing their versatility and importance in modern technology.
