1. It must be able to eliminate the effect of direct light source to prevent the main reflector, secondary reflector and rear-end correcting mirror group in the telescope group from being directly illuminated by light sources outside the viewing angle, such as sunlight.
2. Block the light that is out of the angle of view or that does not follow the designed light path and directly penetrates through the central hole of the main reflector.
Third, reduce the scattered stray light in the system, or the double pass light between the main reflector and the secondary reflector. The focal plane imaging.
Fourth, standardize the visual range of the telescope group. According to the above conditions, the shading system can be classified into the sun-shield, the primary baffle (primary baffle) located in the central hole of the main reflector, the secondary baffle surrounding the periphery of the secondary reflector, and the other There is a sub-structure on each shading element and mechanism to prevent stray light from scattering on the surface of the structure, which is called a light-shielding rudder.
