云南天文台1m红外望远镜的主镜热力学分析

The Thermal Analysis of the Primary Mirror of 1m Infrared Solar Telescope at Yunnan Observatory

云南天文台1m红外太阳望远镜是多功能、多波段的太阳望远镜,望远镜使用过程中主镜的热变形直接关系这系统的光学精度,建立光学系统的光机热结合的分析方法,可以直观的得到热辐射对光学系统的影响结果,使得望远镜的设计阶段就能评估热变形对系统的精度影响,确定光学元件是否满足要求。

Infrared solar telescope with the aperture of lm at Chenjang in Yunnan province is a mult - ipurpose and multi - band solar telescope, the thermal deformation of primary mirror of the telescope is directly related to the optical precision of the system. The establishment of the optics - machine - thermotics analysis method can directly get the effect of the thermal radiation on the optical system and open the door for assessment of the effect of the thermal deformation on the optical system, and allow us to determine whether the optical components can meet the requirement for use at the design stage
