  A plano concave cylindrical lens   is used to condense light in one axis.  A positive plano cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping. If you have any demand, please contact Ecoptik   (also known as BRD Optical).   Plano Convex Cylindrical Lens Descriptions The Plano spherical lens acts symmetrically on the incident light in both directions, while the convex cylindrical lens   acts in only one direction on the incident light.  A typical application is to shape a deformed beam with a pair of plano-convex cylindrical lenses. A pair of positive plano-convex cylindrical lenses can be used to collimate and round the output of the laser diode. Another possible application is to focus the diverging beam onto the

  Ecoptik  (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. These meniscus lenses are useful when used with another lenses to increase or decrease the focal length. This meniscus lens element configuration does not introduce any additional coma or spherical aberrations   Descripion Of Positive&Negative Meniscus Lens Ecoptik  (also known as BRD Optical) provides meniscus lenses  in both positive and negative focal lengths.  On the aspect of shape, it can be divided into convex meniscus lens and concave meniscus lens. On the aspect of the effect, it can be divided into diverging and converging meniscus lens.   Positive Meniscus Lens A positive meniscus lens consists of two curved surfaces with similar radii of curvature and has a positive focal length. Positive meniscus lens are typically used for related applications such as reducing the focal length of another lens, increasing the numerical aperture, etc.In order to reduce spherical ab
