Spectrographic astigmatism correction system |
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.
