Cylindrical lenses are lenses that focus light onto a line and never one point, because the spherical lenses do.
The curved faces of the lens are segments of the cylinder that focus the incoming light about the same dimension causing the image to stretch. Cylindrical lenses can be utilized to correct ocular astigmatism. Considering that the lenses are nonspherical, there's a reduction in chromatic and spherical aberration.


Some regular mirror of the cylindrical lens include bar-code scanning, pc, dye lasers, laser emission, linear detector lighting and optical information-processing. In a light sheet microscope, the lenses are placed facing the objective, creating a light sheet that is employed for imaging.

Cylindrical lens features

Cylindrical lenses are stated in various radius and a number of specifications. Unique glass materials used include Ohara, Schott, Fused Silica, CDGM, ZnS, ZnSe and CaF2. A cylindrical lens might be classified as exclusive and ordinary. The ordinary class incorporates bi-convex cylindrical lens, bi-convex cylindrical lens, planoconvex cylindrical lens, plano-concave cylindrical lens, meniscus cylindrical lens and double concave cylindrical lens.

Unique cylindrical lenses contain cylindrical ellipsoidal mirror, parabolic mirrors, achromatic cylindrical lens and double-curved cylindrical lens. Achromatic cylindrical lens diminishes the chromatic aberration hence giving extra color-correction.

Cylindrical lens might be specially made to meet up the client’s intricate shape requirements. They are able to have rectangular, circular or oblong dimensions. Uv and infrared quartz antireflection coating options can be found for cylindrical lenses. Substrate materials used contain Ohara, Schott, CDGM, JGS1, Corning Fused Silica and JGS2.
