In this paper design and construction of a high-resolution spectrometer is studied. In this spectrometer, a grating is used as a dispersive element for spectral separation. Optical design of spectrometer is done by Zemax, and a 1200 groove/mm grating and a concave mirror  with 70 cm focal length have used in that. The entrance of spectrometer is an optical fiber with FCPC connection which depends on its diameter of aperture the resolution varies. The used detector is a silicon linear array CCD with 3648 pixels. By using a 9μm optical fiber the resolution of this spectrometer is 0.04 nm at 780 nm and it's free spectral range is 27 nm too.

Keywords: Resolution, Grating, Zemax, Spectroscopy, CCD
