High Resolution Échelle Spectrometer (HIRES)




A large instrument, designed by Steven Vogt and attached to the Keck I telescope (see Keck Telescopes), which breaks up incoming light into its component colors and measures the precise intensity of each of thousands of color channels. Operating in the 0.3-1.1 micron wavelength range, it is 10 to 100 times more sensitive than any comparable system and has been used in the detection of a number of extrasolar planets as part of the San Francisco State University Planet Search program.
