Goddard High Resolution Spectrograph
From Wikipedia, the free encyclopedia
(Redirected from High Resolution Spectrograph)
The Goddard High Resolution Spectrograph (GHRS or HRS) was a spectrograph installed on the Hubble Space Telescope. It was replaced by the Space Telescope Imaging Spectrograph in 1997.
- Instrument type: Ultraviolet spectrograph
- Wavelength range: 1050 to 3200 Å (105 to 320 nm)
- Resolving Power (all at 1200 Å)
- Low - 2,000 (0.6 Å, or a Doppler effect of 150 km/s)
- Medium - 20,000 (0.06 Å, 15 km/s)
- High - 100,000 (0.012 Å, 3 km/s)
