Optical filters on board the Space Telescope Imaging Spectrograph (STIS)

摘要

Abstract: The space telescope imaging spectrograph (STIS) instrument is due to be installed on board the Hubble Space Telescope (HST) in 1997. STIS uses 20 filters located on a wheel that can rotate any one of 88 apertures or combination filter/aperture in to the beam path. The instrument incorporates a continuous range of spectral response from the VUV (115.0 nm) to 1 micrometer. Therefore, filters that perform in the VUV are discussed as well as filters that operate in the near infrared. Neutral density filters are also being used for on-board calibration from 300 nm to Lyman-Alpha (121.6 nm). !0
