A dove prism is a kind of image rotator. The image is inverted 180° after the light passes through the prism. In addition, when the prism is rotated with its optical axis, the rotation angle of the image is twice that of the prism.
Generally speaking, dove prism realizes internal total reflection by using the principle of critical angle, so its field of view Angle is limited. At the same time, it is important to keep the reflector clean and use parallel light.
The dove prism is an ideal for image rotation. It create an image inversion in a beam input parallel to the base.
Optical prism, a transparent object surrounded by two planes that intersect but are not parallel to each other, used to split or disperse light beams. Prisms are polyhedrons made of transparent materials (such as glass, crystal, etc.). It is widely used in optical instruments.

According to the shape can be divided into the following: Right Angle, Dove, Rhombic, Penta Prism and special shaped prisms. We can custom optical prism according to your needs.
There are mainly four types of prisms according to their functions, dispersive prisms, deflecting or reflecting prisms, rotating prisms, and offset prisms. Deflection, offset, and rotation prisms are commonly used in imaging applications; diffuser prisms are designed for use with dispersive light sources and are therefore unsuitable for any application requiring high-quality images.
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.
