• Right Angle Prism

    Right angle prisms deviate the line of sight of an optical system by 90 degree. Depending on the orientation of the prism, images will be either correct left-to-right and inverted or erect and reversed left-to-right. Right angle prisms are commonly used in imaging systems to obtain a right angle path bend around obstacles.

  • Littrow Dispersion Prism

    Uncoated prisms are used to disperse light into its component spectrum. Coated prisms are used to deviate the line of sight by 60.

  • Dove Prism

    Dove Prism has two applications. The main application is used as a rotator. It can rotate an image but without deviating the beam. And when the prism is rotated about the input parallel ray through some angle, the image rotaes through twice that angle. It is very important that the application must be used with parallel or collimated beam and the large square reflective surface should be kept very clean. Another application is used as a retroreflector.

  • Rhomboid Prism

    Rhomboid prisms are used to displace a laser beam without changing its direction. In imaging applications, they will displace the optical centerline without inverting the image. The lateral displacement is equal to the length of the prism.The lateral displacement is equal to the length of the prism.

  • Corner Cube

    It has three mutually perpendicular surfaces and a hypotenuse face. Light entering through the hypotenuse is reflected by each of the three surfaces in turn and will emerge through the hypotenuse face parallel to the entering beam regardless of the orientation the incident beam. It is often used to the distance measurement, optical signal process and laser interferometer.

  • Penta Prism

    Penta prism can deviate an incident beam without inverting or reversing to 90 degree. The deviation angle of 90 degree is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, Rangefinding and Optical Tooling.

  • Wedge Prism

    Wedge prisms can be used individually to deviate a laser beam a set angle, or two wedge prisms can be used together as an anamorphic pair. A single prism's ability to deviate the angle of an incident beam is measured in Diopters with 1 diopter deviating the beam 1cm at a 1m working distance. Two wedge prisms can be used as an anamorphic pair for beam shaping (to correct the elliptical shape of diode outputs).

  • Schmidt Prism

    Schmidt prisms are used to invert and revert an image while deviating it through an angle of 45°. Similar in function to Amici prisms, however the 45° deviation makes Schmidt prisms especially useful in eyepiece assemblies and imaging systems requiring a path bend. The aluminized roof surfaces enhance the overall efficiency while the 5 arc second roof angle tolerance increases the prism’s resolution.

  • Equilateral Prism

    Equilateral dispersing prisms are used to separate wavelengths. A light ray is refracted twice as it passes through the prism. Deviation, qd is a function of refractive index, and hence wavelength. Angular deviation Δqd is the difference in deviation for light rays having different wavelengths and varies with prism orientation. Reflection losses are minimized for unpolarized rays that travel through the prism parallel to the base. This condition is called "minimum deviation" and occurs when the angle of incidence at the entrance is equal to the angle of emergence (both angles measured with respect to the surface normals).

  • Roof Prism

    Roof Prisms, also called “amici prisms” or “right angle roof prisms,” do two things: invert the image and bend the line of sight through a 90° angle. They are excellent as prism diagonals in optical systems, because they erect the inverted image. Also ideal for use in spotting scopes, and any optical instrument where it is desirable to take an inverted image from an objective, turn it right side up, and bend it through a 90° angle, to maintain the correct visual orientation.
