high-resolution spectrograph Archives

The Keck Planet Imager and Characterizer (KPIC) connects the Keck II AO system and the Keck/NIRSPEC high-resolution infrared spectrograph (https://www2.keck.hawaii.edu/inst/nirspec/) via a linear bundle of four single-mode fibers spaced by ~800 mas on the sky. Single-mode fibers provide a more stable quasi-Gaussian line spread function. Their small angular size, matched to the diffraction limit (FWHM~50 mas in K band), also provides excellent sky background rejection, as well as reduces the off-axis starlight injection into the single mode fibers. Currently, KPIC uses the Shack-Hartmann Wavefront Sensors for AO. Larger image
