Plano-Concave Cylindrical Lenses are optical elements designed with one flat (plano) side and one inwardly curved (concave) side, which is curved in one dimension. What is Plano-Concave Cylindrical lens? Plano-concave cylindrical lenses are optical elements designed with one flat (plano) side and one inwardly curved (concave) side that is curved in one dimension. Unlike plano-concave spherical lenses or Bi-Concave lenses that affect light in all directions, cylindrical lenses focus or diverge light in only one plane, offering unique control over the light's path. Specifically, plano-concave cylindrical lenses are used to diverge light rays in the dimension parallel to the lens's curved surface. Cylindrical lenses for beam divergence One of the primary functions of Alien Photonics cylindrical plano-concave lenses is to diverge light in one dimension. This property is particularly useful in applications where spreading the light beam in a controlled manner is desired, such as in illumination systems or in the optical path of imaging systems to adjust the field of view. Anamorphic beam expansion using Cylindrical PCV Lenses Alien Photonics cylindrical plano concave lenses are adept at expanding laser beams in one axis, which is essential for correcting the asymmetry of laser beams emitted by laser diodes or other elliptical sources. By expanding the beam in the narrower dimension, cylindrical plano-concave lenses help in achieving a more symmetrical beam profile, which is crucial for applications requiring uniform illumination or precise beam shaping.
