A sphere is defined by a single radius of curvature. Aspheric Lens have at least one aspherical surface. Optical engineers generally think of aspheric surfaces as aspheric, rotationally symmetric surfaces. The radius of curvature of the aspheric surface varies gradually from the center of the lens to the edge.

   The surface profiles of aspheric lenses are not a portion of a sphere or cylinder. Their curvature radius varies with the central axis. Aspheric lenses have unique advantages over spherical lenses. For example, they can improve optical quality, reduce optical components and design costs. They are widely used in optical instruments, images and optoelectronics industries, such as digital cameras, CD players and high-end microscopic instruments.

Difference between aspheric lenses & spherical lenses:

   Aspheric Lenses: Advantages & Disadvantages In a nutshell, aspheric lenses have the following advantages:
They provide a thinner profile
They are lightweight and comfortable
They could be fit into most frames so you have a wide choice of styles
They have a more natural and pleasing appearance
They don't make your eyes look too big or too small
They provide a better peripheral vision by eliminating distortion



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.

Feature:

Applications:

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.
