China Bk7 Uvfs Zf13 Penta Prism Half Penta Prism

Penta Prisms are used to define right angles in optical systems. Penta Prisms, which provide right handed images, feature a ray deviation of 90°. Penta Prisms are five-sided prisms and unaffected by slight movements. Edmund Optics offers a variety of Penta Prisms for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) spectrums.
Qinhuangdao Intrinsic Crystal Technology Co., Ltd can offer features the world's largest inventory of off-the-shelf optical components, including a wide range of Prisms. Edmund Optics' Penta Prisms are offered mounted or unmounted, or in N-BK7 or UV Fused Silica Substrates. C-Mounted Penta Prisms are ideal for easy integration into C-Mount systems. These Prisms are mounted in black, anodized aluminum housings with two female C-Mount apertures. N-BK7 Penta Prisms, which are ideal for applications in the visible spectrum, are offered in a range of sizes or anti-reflection coating options, including MgF2 or VIS 0°. UV Fused Silica Penta Prisms are offered uncoated or with a UV-AR anti-reflection coating. UV Fused Silica Penta Prisms are ideal for applications in the Ultraviolet (UV), Visible, or Near-Infrared (NIR).

The penta prism employs reflection off two surfaces to deviate a light beam by 90° while preserving image parity. The beam deviation is invariant to slight rotation of the prism, making it useful for applications where critical alignment is necessary. Alternate prism configurations include the roof penta, which reverses the parity of the image, and the half-penta, which deviates light by 45°. Penta prisms are commonly used in image erecting assemblies and as laser insertion prisms for advanced surveillance and range-finding applications.

Aluminum, silver, and gold mirror coatings with protective epoxy paint overcoats are commonly applied to the two reflecting faces of the penta prism. Alternatively, the 22.5° incident angle upon the reflecting faces is ideal for dielectric high reflective mirrors and dichroic beamsplitter coatings that operate over wide cone angles.
