TripleSpec

(TSpec)
(near-infrared spectrograph on the Hale Telescope)

TripleSpec is a near-infrared spectrograph covering .095 to 2.46μm, with a spectral resolution of 2500-to-2700. One is installed on the Hale Telescope and another at the ARC 3.5m telescope at the Apache Point Observatory (APO).

I believe it is called "TripleSpec" because after a grating spreads the light by wavelength, it is passed through three prisms to disperse it in the crosswise direction.
