日出（Solar-B）太阳光学望远镜（SOT）对轨道上有机材料释气产生的分子污染物沉积非常敏感。它于2006年9月22日由M-V火箭发射。SOT遥测数据表明，热转储镜（HDM）的温度在头两个月迅速上升，SOT吞吐量在较短的波长线性下降超过一年。这些归因于分子污染沉积降低HDM的太阳能吸收率、主镜和次镜的反射率以及准直透镜的透射率的事实。为了确定主要的污染源和污染的光学器件，进行了分子污染沉积的数值分析。我们发现，主要污染源是准直透镜装置中使用的硅酮密封剂DC 6 -1104。
The Hinode (Solar-B) Solar Optical Telescope (SOT) is sensitive to molecular contaminant deposition resulting from its organic materials outgassing on orbit. It was launched by M-V rocket on 22 September 2006 UT. The SOT telemetry data showed that temperature of the Heat Dump Mirror (HDM) rose rapidly during first two months, and that the SOT throughput at shorter wavelength decreased linearly over one year. These are attributed to the facts that molecular contamination deposition degrades a solar absorptance of the HDM, the reflectance of the Primary Mirror and the Secondary Mirror, and the transmittance of the Collimating Lens. The numerical analyses of molecular contamination deposition were conducted in order to identify a major contaminant source and contaminated optics. We found that a major contaminant source was silicone sealant DC6-1104 which was used in the Collimating Lens Unit.
