Roof Prism Amici Prisms

The roof prism is a reflective optical prism, which contains the part where two surfaces intersect at a 90° angle. The image reflected from the two 90° surfaces is laterally deflected on the axis where the surfaces intersect, using total internal reflection (TIR) to reflect the image. Roof prisms are suitable for use in telescopes or any other application involving image segmentation or deflecting a beam of light 90° to maintain the intended imaging direction. The Tianyang Valley roof prism processing technology is mature and easy to achieve high precision. The accuracy of prisms with a diameter of less than 3 inches can be controlled within 2 seconds. The roof prism is processed through milling, fine grinding, grinding and polishing processes to achieve high-precision mirror flatness and included angle accuracy.

Features of Roof Prism Amici Prisms

Features of Roof Prism Amici Prisms
  • One-stop customized production: Solar Valley processes roof prisms of various sizes and shapes according to customer requirements.

  • Material: Made of H-K9L, or BK7, optical quartz, other optical glass materials can also be used.

  • Roof prism properties: The characteristic of a roof prism is that the beam is split into two, half of the beam hits the first side, then the other side, and the other half of the beam is inverted. Use a roof prism at a certain distance from the focal plane. , the angle between the two surfaces is accurately controlled to 90 degrees, otherwise the image quality will be affected. The advantage of binoculars with roof prisms is that they have straight tubes where the front lens or objective lens is in line with the rear lens or eye lens. Roof prism binoculars are therefore more compact and easier to carry around. It's also easier to seal them, making their internal lenses watertight and less susceptible to dust and damage.

  • Description of product size indicators: Maximum dimensions of roof prism: ≤100×100mm Thickness T≤50mm.

  • Surface defect grade: 60-40, 40-20, 20-10, 10-5. Produced according to customer requirements.

  • Coating: Coating according to customer requirements.
