K9 Dove Prism Right Angle Roof Prism

The right angle prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads, because they are easier to mount, and deform much less than mirror in response to external mechanical stress. As long as acceptance angle limitations for TIR from the roof faces are not exceeded, the right angle prisms can serve as a retro reflector, turning beams back to the original direction.Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.

Prisms Optical Components Right Angle Prism Supplier:ChangChun BRD Optical co., Ltd PARAMETER: Right angle prisms are extremely versatile optical components, commonly used as individual prisms and components of optical assemblies. A beam of light entering the leg of a right angle prism will deviate by a nominal value of 90°, while precise rotation of the prism controls beam alignment. When light enters the hypotenuse of the prism, it is commonly called a porro prism. In this configuration, a light beam will undergo 180° deviation that is invariant in the azimuthal axis, while precise adjustment of the prism controls beam elevation.

Penta Angle Prism are widely used in laser level, Image system, precision system, and optical area. For penta prism, the deviation angle of 90 is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled, we can produce high precision penta angle prism,and make coating according to customer's request.

Dove prism is a kind of reflection prism used for image reflection.Dove prisms are formed by truncated rectangular prisms.A beam of light enters one of the slanted faces of the prism, fully reflects from inside the longest (bottom) face, and then exits from the opposite slanted face.The image through the prism is flipped, and since only one reflection occurs, the handedness of the image is reversed.Dove prisms have an interesting property that when they rotate along the vertical axis, the transmitted image rotates twice as fast as the prism.It is very important that applications use parallel or collimating beams and keep the large square reflector very clean.Another application is as an inverse.

Photonchina has been focusing on dove prism manufacture for more than decades in order to meet demands of customers worldwide in applications ranging from image displaying to fiber communications. Dove prism is a type of reflective prism which is used to invert an image. These prisms are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image's handedness is changed to the opposite sense. 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 performance, you may use dove prisms with collimated light. The top surface of each dove prism is ground and the longest length features an unbeveled sharp edge. Dove Prisms are offered uncoated, with anti-reflection coated diagonal faces, or with aluminized diagonal faces. Aluminized dove prisms feature a protected aluminum coating with black Krylon paint on the diagonal faces and are ideal for displaced retroreflection. They provide a u-turn for incident laser beam light.
