(The extreme ultraviolet is defined to be between about 100 and 1,000 angstroms.) It had four telescopes with gold-plated mirrors, the design of which was critically dependent on the transmission properties of the filters used to define the EUV bandpasses. The combination of the mirrors and filters was selected to maximize the telescope’s sensitivity to detect faint EUV sources. Three of the telescopes had scanners that were pointed in ...(100 of 147 words)
