Fused quartz Plano convex cylindrical lens


  • The quartz plano convex cylindrical lens can turn the light from a luminous point into a line. The surface light can be generated by placing two plano convex lenses perpendicular to each other or in the intersecting direction. The total focal length is the sum of each focal length.
  • Fused silica plano convex cylindrical lens has high transmittance from ultraviolet to near infrared (190nm-2200nm).
  • The typical application of Plano convex cylindrical lens is to use a pair of cylindrical lenses to shape the deformed beam. A pair of flat convex cylindrical lenses can be used to collimate and round the output of laser diodes. Another possible application is to focus the divergent beam onto the detector array with a single cylindrical lens. In order to minimize the spherical aberration, when the collimated beam converges into a line, the collimated light should be incident from the curved surface of the lens, while when the collimated light source is quasi linear, the linear light source should be incident on the plane of the lens.
