Descripción
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) will
observe approximately 100,000 giant stars in the Milky Way with a
dedicated fiber-fed (300 fibers from the Sloan 2.5-m telescope)
near-infrared (1.5-1.7 micron) high resolution (R 22,500) spectrograph
as part of the Sloan Digital Sky Survey III (SDSS-III). By observing in
the near-infrared, APOGEE can uniformly sample all Milky Way stellar
populations (bulge, thin/thick disks and halo) in the same survey to
dramatically improve our understanding of the kinematical and chemical
enrichment history of our galaxy. The instrument design includes several
innovations: a novel fiber gang connector that allows simultaneous
optical connection of 300 fibers from the instrument into swappable plug
plate cartridges, the first deployed mosaic volume phase holographic
(VPH) grating, and a very large ( 0.4-m) aperture six-element refractive
camera incorporating crystalline silicon elements to image 300 spectra
onto three HAWAII-IIRG detectors simultaneously.
