This spectrometer has a resolution of 15 Å over the spectral region 0.6-1 µ, and can obtain electronically read out spectra at selectable scanning rates of up to 10,000 scans/sec. The technique of using an image dissector as the detector holds promise of even faster scan rates. The NEI of 4.6 × 10-5 W/cm2 at 0.8 µ is comparable with that of ir streak films. The instrument is ruggedized for field and airborne use.
