PARAMETER:
Cylinder Lenses are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image. Cylinder Lenses are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.

Cylindrical lenses are either plano-convex or plano-concave in form and rectangular in shape. These lenses are used in applications requiring magnification only, such as in transforming a point image into a line image or changing the height of an image without changing its width or vice versa. Therefore serves a variety application, such as slit line detector array illumination, bar code scanning, holography, optical information processing and computer, laser projection.

PARAMETER:
A plano concave cylindrical lens is used to expand light in on axis. A negative cylindrical lens is able to diverge collimated input light away from a line. Plano-concave cylindrical lenses are used for one-dimensional compression of images, anamorphic beam shaping, and laser line generation.
Specification
PARAMETER:
Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses.

Optical Glass Plano Convex Cylindrical Lens
A Optical glass Cylinder Lenses is used to condense light in one axis. A positive 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.

PARAMETER:
Meniscus Cylindrical Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens.

Centration
A plano-concave cylindrical lens has curvature in the vertical direction, functioning as a concave lens, while having no curvature in the horizontal direction. It is used to magnify a beam in a single direction, such as transforming a laser beam into a line or sheet of light, or altering the height of an image without changing its width. When combined with a concave cylinder lens, it can be used to shape the elliptical beam of a semiconductor laser into a circular one, among other applications.
Features of Plano Concave Cylindrical Lens
The cylindrical concave lens forms a diverging line-shaped virtual image and is primarily used to control the size of a beam in one direction. This lens consists of a flat surface and a concave cylindrical surface, with a negative focal length. Light passing through the axial meridian does not experience a change in convergence, but light passing through the refractive meridian does experience a change in convergence.
Applications of Plano-Concave Cylindrical Lenses
Beam Shaping:
Plano-concave cylindrical lenses are often used to convert collimated laser beams into line beams. By orienting the curved surface of the lens towards the light source, spherical aberration can be minimized, thereby achieving beam shaping.
Image Shaping:
A pair of plano concave lenses can be used for image shaping, particularly when it is necessary to shape a point source in one-dimensional direction.
Laser Scanning Systems:
In laser scanning systems, about plano concave lens are used to adjust the beam shape to meet scanning requirements. They can also be combined with other optical elements to achieve complex beam shaping functions.
Spectral Analysis:
During spectral analysis, plano-concave cylindrical lenses are used to adjust the divergence or convergence angle of the beam to meet different measurement needs.
