太阳光谱望远镜散射光初步测定

The Measurement of Scattering Light of the Solar Spectrum Telescope

报告了云南天文台太阳光谱望远镜散射光的测定，用零级光谱测定仪器轮廓的方法得到白光散射光最大为８％，平均为５％，估计光路系统改进后仪器散射光将减少。

The measurement of the scattering light of the solar spectrum telescope at Yunnan Observatory is reported in this paper.It is shown that the maximum and the average value are 8% and 5% respectively by means of the measurement of the outline for the zero class spectrum.It is expected that the scattering light will be decreased with the improved optical system.
