Abstract
The invention provides a supporting structure for a primary mirror of a large-caliber reflector. The supporting structure for the primary mirror of the large-caliber reflector is characterized in that a round reflecting mirror body is arranged at the center of the round mirror, triangular lightening holes and honeycombed lightening holes are formed in the back side of the mirror in a combined mode, reinforcing ribs are arranged in the lightening structure in a criss-cross mode, supporting points are arranged on the circumference with the center of the circle of the mirror as the center, and the number of the supporting points is a multiple of three. Due to the fact that the triangular lightening holes and the honeycombed lightening holes are formed in the back side of the mirror in the combined mode, the effects are remarkable in the two aspects of dead-weight deformation and thermal deformation; the requirements for the rigidity and the strength of the primary mirror and the requirement for dimensional stability to heating are all met, and it is guaranteed that the position precision and the surface shape precision of the primary mirror are high enough.
Description
Technical field
The design relates to large caliber reflecting mirror primary mirror support structure designs, belongs to optical technical field.
Background technology
Long-focus heavy caliber space camera generally adopts reflective optical system, heavy caliber principal reflection mirror support technology is one of gordian technique of space camera development always, how to make master lens system both meet rigidity, requirement of strength, meet again thermal dimensional stability requirement, mirror structure lightweight is one of key point of support technology simultaneously.
Summary of the invention
According to above-mentioned requirements, the design's object is to provide a kind of large caliber reflecting mirror primary mirror supporting construction, effectively to reduce primary mirror weight.
For achieving the above object, the design realizes by following technological means:
A kind of large caliber reflecting mirror primary mirror supporting construction, it is characterized in that: be provided with circular reflector at circular Jing Ti center, the open back form that mirror body adopts triangle lightweight hole to combine with honeycombed lightweight hole, in lightweight structure, be provided with crisscross reinforcement, on the circumference in the center of circle, be provided with taking three strong points as multiple taking the mirror body center of circle.
Preferably, described a kind of large caliber reflecting mirror primary mirror supporting construction, is characterized in that: described Mirror blank materials is gel RB-SiC.
