What is a Cylindrical
Lens?
Like all lenses, this lens
focuses light, but it differs in that it focuses the light in a line instead of
to a single point as a spherical lens does. The curvature of a Cylindrical lens
is sectioned so when the light passes through it is projected onto a line that
intersects the surface in a parallel fashion and on a plane tangent. The lens
compresses the image so that it is perpendicular to the line and projects the
image in a parallel direction. This cylindrical lens is often the solution for
people who have ocular astigmatism.

Capabilities
A Cylindrical lens is not
shaped like a spherical lens, because of this, the cylindrical lens is used in
many industries.It can be used in barcode scanning, holographic applications,
linear detection, laser emissions, and of course there are many optical uses,
as well as many. Other uses.
Cylindrical Lens Use
Shanghai Optics is a
manufacturer of cylindrical lenses made for a variety of specifications. They
make lenses with different radius and of various types of glass materials which
range from Schott, to ZnS. We can produce either convex or concave cylindrical
lenses. These can include:
Plano-Convex
Plano-Concave
Bi-Convex
Double Concave
Meniscus Cylindrical lens
Others
Specialized Work
We also manufacture
specialized lenses such as the Achromatic Cylindrical lens, the Parabolic
Mirrors and others in any shape needed. At times, some of our customers have
special lens requirements and need a complex shape such as a cylindrical lens
in the shape of a fan, or an Off-Axis Mirror. The glass materials we use vary
but can include ultraviolet or infrared quartz crystals
Shanghai Optics uses
specialized CGH Cylinder Nulls for most of their lenses. This combined with
their extensive lens testing and the Zygo interferometer, the company is able
to meet all manufacturing obligation with clients. They also offer all
interferogram testing results and inspection reports when required.
The Shanghai Optics
Commitment
We offer factory standard
Cylindrical Lens products for many different health and industry-related needs.
