Uncoated Roof Prism
What is the definition of the Roof Prism?
The Roof Prism is a common optical prism with a “ridge-shaped” reflective surface.
It not only enables the reflection of the light path but also can invert the image and flip it left and right.
Therefore, the Roof Prism is widely used in optical instruments that require a compact structure and accurate imaging.
The working principle
When light enters the prism, it undergoes multiple total reflections, and the image achieves a change in direction while maintaining clarity and brightness:
- Image inversion: Upside-down.
- Image flipping: Left-right reversal
The advantages of the roof prism
- Compact structure: The prism can effectively reduce the volume and weight of the optical system.
- High-precision imaging: The prism can make a clear positive image effect.
- Multifunctionality: Equipped with both optical path reversal and image flipping functions simultaneously.
- Widely applicable: The prism is suitable for portable and high-end optical devices.
The application fields of the prism
- Telescope: The prism achieving true image formation, making the structure smaller and more lightweight.
- Laser rangefinder: It helps adjust the direction of the optical path and improves accuracy.
- Optical instruments: such as microscopes and observation systems.
- Photographic equipment: The prism is used in the viewfinder system for image adjustment.
