BWJ pentagonal prism Introduction: A pentaprism is a pentahedral prism with a 90 ° ray deviation and right-handed image. It has two important characteristics. Firstly, the beam of light is reflected twice inside the prism, allowing an image to be transmitted through a vertical angle without flipping like a right angle prism (i.e. without changing the rotation of the image). Secondly, a pentagonal prism is a constant deviation prism, which means that regardless of the angle between the light and the optical axis, all light passing through the effective aperture is equally deflected by 90 degrees, so the deflection is independent of the orientation of the prism. Technical parameters: Material: optical glass Dimensional tolerance:+0/-0.01~+0/-0.1mm Thickness tolerance: ± 0.01~± 0.1mm Face type: λ/ 10~ λ/ 2@632.8nm Finish: 10/5~60/40 Angular accuracy:<3 "~3 ' Effective aperture:>90% Chamfer: Coating: antireflective film, reflective film
