The Near-Infrared High Throughput Spectrograph (NIHTS)is in operation on the 4.3 m Lowell Discovery Telescope(LDT)in Happy Jack, AZ. NIHTS is a low-resolution spectrograph(R∼200)that operates from 0.86 to 2.45 microns.NIHTS is fed by a custom dichroic mirror which reflects near-infrared wavelengths to the spectrograph and transmits thevisible to enable simultaneous imaging with the Large Monolithic Imager (LMI), an independent visible wavelengthcamera. The combination of premier tracking and acquisition capabilities of the LDT, a several arcminutes field of viewon LMI, and high spectral throughput on NIHTS enables novel studies of a number of astrophysical and planetaryobjects including Kuiper Belt Objects, asteroids, comets, low mass stars, and exoplanet hosts stars. We present asummary of NIHTS operations, commissioning, data reduction procedures with two approaches for the correction oftelluric absorption features, and an overview of select science cases that will be pursued by Lowell Observatory,Northern Arizona University, and LDT partners.
