prisms

           Prisms are generally divided into Corner Cubic Prism、Optical Corner Cube Prism、Corner Cube Prism、Glass Corner Cube Prism、Beam Deviation Prisms、Inked Dispersion Prism.

• AMICI reflecting prism also known as roof prism or right prism roof prism, it deflects the light beam by 90 degrees and reverses the image. The prism is therefore ideal for erecting images inverted by the objective lens. Amici prisms, also known as "roof prisms" or "right-angle roof prisms", restore and reverse images and bend the line of sight through 90° angles. Ideal for sight scopes, and any optical instrument that needs to take an inverted image from an objective, turn it up on the right side and bend it through a 90° Angle to maintain the correct visual direction. For linearly polarized incident light, the light coming out of the uncoated Amici prism is a mixture of the two elliptical polarizations, which can lead to reduced contrast and resolution in some applications. Silver-plated Amici roof prisms eliminate these problems.
• "A pentaprism can deviate from the incident beam without reversing or reversing to 90. The deviation Angle of 90 is independent of any rotation of the prism around an axis parallel to the intersection line of the two reflecting surfaces. Penta prisms are commonly used for plumb level, measurement, alignment, ranging and optical tools.
• Therefore, the deviation Angle of 90° is independent of the direction of the prism, so it is particularly important in applications where the direction of the prism cannot be accurately controlled. Since total internal reflection geometry cannot be used, the reflective surface must be coated with a metal or dielectric coating. Standard Penta prisms have reflective surfaces coated with aluminum or reinforced aluminum (see section coating). Sometimes, the surface of the coating is painted black.

• The above general tolerance specifications provide guidance on the manufacturing capability of optical elements in the size range of 3 to 76.2mm. Manufacturing restrictions are not absolute; Tighter tolerances may be possible. Component specific tolerances may vary depending on component size, shape and/or material.
