Cylindrical Lenses

Cylindrical Lenses

Cylinder lenses are lenses with a finite radius of curvature in one axis and an infinite radius of curvature in the orthogonal axis.  If you think of a soup can cut in half from top to bottom, that will give you an idea of what a cylinder lens is.  Conventional spherical lens processing equipment cannot be used for manufacturing cylinder lenses and processing time is slower.  Typically, cylinder lenses are Plano on one side, but custom configurations are available. We also manufacture custom solutions in case one of our many standard lenses do not meet your requirements.

  • Cylindrical Convex Lenses

    Description

    Cylindrical Convex lenses also known as Positive cylindrical lenses. These focuses light into a line instead of a point, as a spherical lens would. The curved face of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to the intersection of the surface of the lens and a plane tangent to it. OptoSigma manufactures a large variety of cylindrical lenses in various sizes and focal lengths, and in both NBK7 and Fused Silica.

  • Cylindrical Concave Lenses

    Description

    Cylindrical Concave lenses also known as negative cylindrical lenses. These focuses light into a line instead of a point, as a spherical lens would. The curved face of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to the intersection of the surface of the lens and a plane tangent to it. OptoSigma manufactures a large variety of cylindrical lenses in various sizes and focal lengths, and in both NBK7 and Fused Silica.

  • Acylinders

    Description

    Acylinders - aspherical cylinder, denotes cylindrical-surface-shaped lenses, the cross-section of which differs from the circular shape. In practice, plano-concave and plano-convex cylinders are used as well as those with a spherical or aspherical reverse. In contrast to a lens, an aspheric cylindrical lens does not concentrate incident light into one focal point, but along a focal line without the influence of spherical aberrations. Advantages include; minimization of aberrations, efficiency increase, reduction of the total number of optical components within optical systems. Cylindrical Lenses are often used in pairs for beam shaping in a variety of applications.
