Optical Cylindrical Lens

A cylindrical lens used in many industries is typically used to focus, condense
or expand incoming light. A cylindrical optical lens has one cylindrical
surface, causing light to be focussed in a single dimension or axis. It can
also be used to expand the output of a laser diode into a symmetrical beam.
Cylindrical optical lenses are technically more difficult to manufacture than
spherical or flat lenses which is why BRD Optical uses state-of-the-art
polishing techniques alongside stringent lens assessment to manufacture each
lens.

The cylindrical optical lenses are typically rectangular, square, or circular
and of either a plano-convex or plano-concave design. BRD Optical's cylindrical
optical lenses combine low wedge with high surface accuracy. As one of the best
optical components manufacturers, we assess the quality of each individual lens
using Trioptics centration measurement and a Zygo GPI interferometer. All BRD
Optical lenses are available both uncoated or coated with a broad range of high
durability, low loss AR coatings, and can be manufactured to 20-10 surface
roughness.

Here are the different types of cylindrical lenses, such as plano concave
cylindrical lens, plano convex cylindrical lens and achromatic cylindrical
lens.


Optical Cylindrical Lens Applications
Cylindrical optics lens can converge or diverge light beams in a single axis.
Cylindrical lens is used in
many industries and fields such as optical metrology, laser scanning,
spectroscopy, laser diode output beam shaping, and light-sheet illumination
microscopic imaging.
Form the collimated light source into a line light source
This is the most widely used cylindrical lens. Taking a plano-concave
cylindrical lens as an example, it can be a beam of collimated light that
expands into a linear light source according to the magnification.
There is also cylinder lens for astigmatism. Collimation of diode output beam
The output beam of the laser diode diverges in an asymmetrical form, and its
collimation work is more challenging. For example, for a diode light source
with a divergence angle, if only a standard spherical lens is used, it can only
be collimated in a single direction, and divergence or convergence will occur
in the other direction. Using cylindrical optical mirror can decompose the
problem into two one-dimensional directions. By combining two orthogonal
cylindrical mirrors, the two directions can be collimated simultaneously.


Optical Cylindrical Lens FAQS
What Is Difference Between Spherical And Cylindrical Lens?What Is Difference
Between Spherical And Cylindrical Lens?
Spherical lenses are lenses taken out from a sphere such as a ball. Where as,
cylindrical lenses are lenses taken out from a surface of a cylinder like a
tumbler. Cylindrical lenses have an axis associated with them. Both, spherical
and cylindrical power can keep changing through life.
