EUV-IR telescope study
Abstract
The optical properties of a telescope providing fields of vision from seconds of arc to degrees were studied. The radiation passes the telescope nearly parallel and enters a spectrometer for dispersion. The optical properties of different telescope spectrometer combinations were geometrically analyzed by a ray tracing method. The range of available spectrometers is so wide that for a variety of applications spectroscopic measurements can be carried out with modest or higher spectral and spatial resolutions, and that from the soft X-ray through the near infrared spectral regions.
