Aroof prismis a reflective optical prism containing a section where two faces meet at a 90° angle. Reflection from the two 90° faces returns an image that is flipped laterally across the axis where the faces meet.
The roof prism is characterized by that the beam is split in half; half of the beam hit the first face, and then the other side, while the other half of the beam is inverted. Thus, a roof prism can be used with distance to the focal plane, or slight distortions will be introduced. In addition, the included angle between the two surfaces must be very close to 90, or the image quality will be regarded.
Roof prisms are suitable elements for telescope or any other applications that involve image splitting, or bending beam by 90°for maintaining the expected imaging direction.Commonly the processing technology of the right angled roof prism is mature, it is easy to achieve high accuracy, and the accuracy of 1 ~ 2 inch in diameter prism can be controlled within 2 seconds.
Anamorphic Prism An anamorphic prism pair is a pair of prisms which is usually used for reshaping the profile of a laser beam. For example, the elliptical beam from a laser diode can be transformed into a beam with circular cross-section, as is needed for many applications, by ...
Optical Prism, a transparent object surrounded by two planes that intersect but are not parallel to each other, is used to split light or disperse light beams. An optical prism is a polyhedron made of transparent materials (such as optical glass prism, optical crystal prism, ...
Dove prisms have an unusual and very interesting characteristic , if you look through the prism and rotate it around a longitudinal axis, the image rotates through twice the angle through which the dove prism itself rotates. For optimal peformance, use dove prisms with ...
