Roof Prisms – Image Erection & Beam Folding
Detailed Description:
Roof Prisms (Amici Prisms) feature a “roof” structure of two perpendicular reflective surfaces, which invert and revert the image while folding the optical path by 90°. They are widely used in binoculars, telescopes, and periscopes to erect inverted images and compact the system size.
Key Specifications:
Materials: BK7, H-K9L, Fused Silica
Size: 10mm – 100mm Angle
Tolerance: ±1′ ~ ±5′
Surface Quality: 40/20, 20/10
Reflectivity: >98% (protected Al/Ag coating)
Coating: Reflective coating on roof surfaces, AR coating on input/output faces
Image Rotation: 180° image reversion
Applications: Binoculars, telescopes, periscopes, surveying instruments, optical rangefinders, imaging systems.
