The satellite was built by NASA's [[Goddard Space Flight Center]]. Its telescope was constructed by a consortium led by [[Lockheed Martin]]'s Advanced Technology Center. The optics were designed and built to a [[State of the art]] surface finish by the [[Smithsonian Astrophysical Observatory]] (SAO). The telescope has a {{cvt|30|cm}} aperture and 1024 × 1024 [[charge-coupled device]] (CCD) detector giving an 8.5 [[Minute and second of arc|arcminute]] [[field of view]] (FoV). The telescope is designed to take [[correlated]] images in a range of wavelengths from [[visible light]] through the [[Lyman alpha line]] to far [[ultraviolet]]. The different wavelength [[passband]]s correspond to [[Plasma (physics)|plasma]] emission temperatures from 4,000 to 4,000,000 [[Kelvin|K]]. The optics use a special multilayer technique to focus the difficult-to-reflect [[extreme ultraviolet]] (EUV) light; the technique was first used for solar imaging in the late 1980s and 1990s, notably by the [[MSSTA]] and [[NIXT]] [[sounding rocket]] payloads.
