aspheric cylindrical lenses


Cylindrical lenses, as the name suggests, are lenses that exhibit a cylindrical shape in at least one part. Unlike spherical lenses, which uniformly focus or spread light in all directions, cylindrical lenses specialize in directing light in a single dimension. This unique characteristic makes them indispensable in certain scenarios where other lenses fall short.

Cylindrical lenses come in various materials, including fused silica (JGS1, Corning 7980, JGS2), optical glass (BK7, B270, H-K9L from Ohara, Schott, CDGM, or Corning), 

IR materials (MgF2, Ge, CaF2, Si), and other options like optical plastics and sapphire.
