Three medium-band filters for use with NRM provide spectral information to characterize the temperature and gravity of objects
The design GR700XD grism is optimized for spectroscopy of transiting exoplanet systems between 0.6 and 2.5 microns. This region includes strategic molecular features like
H2O and CO2. Mild defocus provided by a built-in lens and the absence of a slit permits extraordinary accuracy.
