摘要: An optical input system for correcting astigmatism introduced by off-axis reflectors in a spectrograph includes an aspheric mirror producing a correcting factor which compensates for the spectrograph distortions and enables the spectrograph to produce multiple astigmatic light images at its two-dimensional charge-coupled-device output.

摘要: A monochromatic spectrometer for evaluating contamination changes in the surface condition of lenses, reflectors and similar optical samples in the vacuum of a space mission includes a vacuum ultraviolet beam source redirected from a dispersion grating through a test station and reflected from a mirror to a photodetector. A rotatable carrier supports two or more optical samples, both transmissive and reflective and selectively positions one sample at a time at the test station so that the selected sample modifies the VUV beam according to its surface condition. The mirror is movable from a first position in which it reflects the beam transmitted through a sample to second position in which it reflects the beam reflected from a sample. The sample condition measured by the photodetector, the position of the rotatable carrier and mission elapsed time are recorded in a memory for re-transmission or later read out.
