云南天文台进口钙色球太阳滤光器原理和损坏元件分析及其修复

Analysis of the Principle and the Damaged Components of the Imported Solar K-Filter at Yunnan Observatory

云南天文台进口钙色球太阳滤光器除1.2A外,0.3A和0.6A主要工作带宽均无出射光线,损坏严重。本文对其原理及其内部结构进行了较详细的分析,列出了损坏元件的几种可能性。依此分析修复了该滤光器。

Except for the 1.2 A, the main optical working band widths, 0.3A and 0.6A, of the imported solar K-filter at Yunnan observatory have no outgoing rays and the damage of the filter is quite serious. In this paper, the princpie and the inside structure of the filter are analysed in more detail, and several possibilities of the fauly components are proposed. According to the analyses, the filter has been repaired.
