UV Fused Silica Roof Prism Basic structure and principles of roof prisms. Roof surface: one of the reflective surfaces of a prism is designed as a "roof " (similar to the angle of two sloping surfaces of a roof, usually 90 ), and these two sloping surfaces flip the direction of the light through secondary reflections, thus correcting for left-right inversion of the image. Optical path adjustment: after many times of total reflection inside the prism, the light ray outgoing direction is parallel to the incoming direction...
