N-BK7 pentaprism
A prism that forms an image with a 90° deviation in the light path through two reflections, without inversion or left-right reversal.
The pentaprism has the function of deflecting the light path by 90° through two reflections, and the image at this time is upright and not laterally inverted. The two reflective surfaces are coated with aluminum and are protected by Inconel and a black paint finish. The two incident and exit surfaces are treated with a specific anti-reflective coating (MgF2 single or VIS 0° multi). Even if the prism tilts, undergoes volume changes due to thermal expansion, or vibrates during movement, it does not affect the 90° deflection direction relative to the incident light (constant deflection angle), making it suitable for use in surveying instruments and refractometers. ■ 90° constant deflection angle prism ■ Forms an upright image ■ Optical tool for defining right angles ■ Additional pentaprisms are also available in the lineup *The catalog of Edmund Optics Japan can be downloaded from the link below.
