Optical Cylindrical Lens
Acylindrical lensis a
lens which focuses light which passes through on to a line instead
of on to a point, as a spherical lens would. The curved face or
faces of a cylindrical lens are sections of a cylinder, and focus
the image passing through it onto a line parallel to the
intersection of the surface of the lens and a plane tangent to it.
The lens compresses the image in the direction perpendicular to
this line, and leaves it unaltered in the direction parallel to it
(in the tangent plane).
Cylindrical lenses can be used to correct ocular
astigmatism, although toric lenses are more commonly used. They can
also potentially be used in solar water heating installations, such
as a plastic pillow-type solar water heater. They are used to
correct the output from diode lasers, to produce a round beam from
the diode's elliptical output.
