    Optical Big Size Right Angle Prisms N-Bk7 Silver Reflective ...
    An N-BK7 Paul prism (often referred to as a Porro prism or right-angle prism in specific configurations) is a widely used optical component designed to deviate light by
    90∘90 raised to the composed with power
    90∘
     or
    180∘180 raised to the composed with power
    180∘
     and invert/revert images. Made from high-purity N-BK7 borosilicate glass, it offers excellent visible light transmission, low cost, and high-quality imaging, making it ideal for binoculars and imaging systems. 
    Key Characteristics of N-BK7 Paul/Right Angle Prisms: 
    • Material: N-BK7 is a common, cost-effective, high-transparency optical glass with low bubbles and inclusions.
    • Function: Typically used to bend light paths by
      90∘90 raised to the composed with power
      90∘
       or, when used in pairs (Paul prism system), to invert/revert images and bend them
      180∘180 raised to the composed with power
      180∘
      .
    • Image Orientation: Generally produces a left-handed image.
    • Surface Quality & Coatings: Commonly available with a 40-20 or better surface quality. Options include uncoated, or with Aluminized or AR coatings.
    • Applications: Ideal for binoculars, microscopes, and various imaging applications, particularly when budget is a factor but good performance is required. 
    While BAK4 prisms are known for higher refractive indices that minimize vignetting at the edge of the exit pupil, N-BK7 is often preferred for its lower cost and higher transparency, providing excellent, bright images for many optical systems.
