Slit Assembly

TripleSpec features a fixed slit assembly of width and length 1.1” and 26.3”, respectively. The primary longslit assembly is accompanied by two flanking outriggers, which are 1.0” square slit boxes 4.6” offset from the main slit aperture. These outriggers are used for better defining a spatial-spectral wavelength calibration (in the X-Y plane), thereby allowing a better interpolation of the spectrum background.
