Optical Glass Roof Prism

Characteristic for a roof prism is that the beam is split in half, with one half of the beam hitting first one face then the other face, while it is invert for the other half of the beam. Therefore, a roof prism can be used only with some distance to focal planes, or the "edge" of the roof would introduce slight distortions. Furthermore, the angle between the two faces has to be very close to 90°, or image quality would be degraded.

Key Features:

  • Material: High-quality optical glass (e.g., BK7, fused silica)
  • High Precision: Accurate angles and surfaces for optimal light manipulation
  • Compact Design: Ideal for modern optical systems
  • Durable Construction: Scratch-resistant and thermally stable materials
  • Customizable Options: Available in various sizes, coatings, and designs
  • Applications: Imaging systems, binoculars, telescopes, and laser equipment

Applications:
The Optical Glass Roof Prism is widely used in

  • Binoculars and telescopes for image correction
  • Laser systems for beam deflection and alignment
  • Imaging systems for high-precision optical paths
  • Industrial optical instruments requiring compact and accurate prisms
