Astronomical research, such as studying the properties of stars or searching for and studying exoplanet, requires high-resolution spectral data of celestial objects. For this reason, NARIT has developed a high-resolution spectrograph, which has a fiber-receiving part, uses prisms and gratings to separate the light spectrum, and has a resolution of more than 70,000. It has now been installed and tested with the 2.4-meter national telescope.
