| 英文摘要 | Full-disc vector magnetograph (FMG) is one of the main loads in the Advanced Space-based Solar Observatory. FMG is used to realize scientific goals of observing full-disk vector magnetic field with center wavelength of 532.4 nm. The optical system of FMG consists of polarized optical system and imaging optical system, and the imaging optical system composes of the front window and telescope system. The front window has the capability for providing proper situation for scientific observation by absorbing high energy of solar irradiance coming from space while reflecting wavelength of non-scientific investigation beyond wavelength of 532.4±5 nm. The study analyzed the influence of complex space environment on optical glasses. As a result, the material of fused silica, while two pieces of flat glass parallel with 3mm separation structure and thickness of 15mm are determined. Finally, the results show that design for the front window meet the required specifications. © 2019 SPIE. |
