The Facility IR Spectropolarimeter(FIRS) is a multi-slit spectropolarimeter designed for the Dunn Solar Telescope (DST) at the National Solar Observatory on Sacramento Peak (NSO/SP) in New Mexico to study magnetism on the solar surface. The instrument samples adjacent slices of the solar surface using four parallel slits to achieve high cadence, diffraction-limited, precision imaging-spectropolarimetry. Due to the versatile, multi-armed design of the spectrograph, up to four spectral lines at visible and infrared wavelengths, covering four different heights in the solar atmosphere, can be observed simultaneously. In this poster-paper we will describe the design, capabilities, and performance of the instrument.
