Abstract: An optical structure is provided including a turning unit and a binocular unit which are sequentially arranged along an optical path direction. The turning unit includes a right-angle roof prism. The binocular unit includes a prism/lens group, a first right-angle prism, a second right-angle prism, and an ocular. The prism/lens group includes a small objective lens, or the first right-angle prism and the second right-angle prism are replaced by a rhombic prism. The optical structure is designed as “inverting-inverting”, and the right-angle roof prism shortens an optical length of an internal optical path of the turning unit by about half, which is more conducive to the reduction of the light vignetting of an optical path of observation. Two internal reflections prevent a mirroring phenomenon, and turn an image by 180 degrees, so that an inverting prism can be omitted from the binocular unit.
