国际日地物理学（ISTP）使命任务的远紫外成像仪旨在对极光的四个特征成像：130.4和135.6纳米的O I线以及140和160纳米（LBH长）以及160和180纳米（LBH长）之间的N2 Lyman-Birge-Hopfield（LBH）波段。本文报道了用于ISTP FUV成像仪的窄带和宽带滤光片的设计和制作。为O-I谱线设计和制造的窄带滤光片的带宽小于5 nm，在130.4和135.6nm处的峰值透射率分别为23.9%和38.3%。针对LBH波段设计和制作的宽带滤光片的透过率接近60%。所有滤光片的带外波长阻挡优于5 x 10（-3）%，121.6 nm处的透射率小于10（-6）%。
The far-ultraviolet (FUV) imager for the International Solar Terrestrial Physics (ISTP) Mission is designed to image four features of the aurora: O I lines at 130.4 and 135.6 nm and the N2 Lyman-Birge-Hopfield (LBH) bands between 140 and 160 nm (LBH long) and 160 and 180 nm (LBH long). We report the design and fabrication of narrowband and broadband filters for the ISTP FUV imager. Narrowband filters designed and fabricated for the O I lines have a bandwidth of less than 5 nm and a peak transmittance of 23.9 and 38.3% at 130.4 and 135.6 nm, respectively. Broadband filters designed and fabricated for LBH bands have the transmittance close to 60%. Blocking of out-of-band wavelengths for all filters is better than 5 x 10(-3)% with the transmittance at 121.6 nm of less than 10(-6)%.
