Custom-made Sapphire Quartz JGS1 Glass Laser Round Cylindrical Rod Lens

What is a cylindrical lens?

The cylindrical lens can change the size of light due to its elongated shape. What makes cylindrical lenses different is that their surfaces are cylindrical.
Since only one axis has a spherical radius, light converges, amplifies, or expands in only one direction. Since the light is concentrated in one dimension, the image is stretched.
The cylindrical lens can be a plano convex lens or a plano concave lens, the former will focus the beam, and the latter will expand the beam. According to your needs, you can choose the cylindrical lens suitable for your application needs.

Cylindrical lens is used to correct astigmatism in the optical system, and, in rangefinders, to produce astigmatism, stretching a point of light into a line. It is usually used in barcode scanners, objective systems and other optical systems.

Application

1 . Correcting Astigmatism

One of the main applications of cylindrical lenses is in ophthalmology, specifically, to correct astigmatic vision.  When a person presents astigmatic vision, it is usually the result of a corneal deformation. An astigmatic cornea will have different focal points at different axes. It is then possible to use a cylindrical lens to change the focal point of one of the axes to overlap the second one.

2 . Laser Line Scanning

This is a technique that is used to capture the  shape of a 3D object into a digital copy.  It is particularly useful in manufacturing, prototyping, landscaping, and architecture.  This scanning technique measures the deformation of a straight line created by a cylindrical lens when it is incident into a non-flat surface.  By using cameras and triangulation, it is possible to measure the changes in the shape of our laser line and therefore estimate the shape of the object that we are measuring.  If you would like to learn more about Laser Line Scanning please leave a comment.

3. Laser Scanning Microscopy

They are usually used in combination with acousto-optic deflectors, where the focal point of a variable lens (the acousto-optical elements) can change its position laterally without the use of movable parts.  The cylindrical lens corrects the image and helps focus the light spot onto the correct plane for laser scanning microscopy.
