The invention relates to the technical field of nuclear fusion, in particular to a high-resolution measuring device for measuring ion temperature and rotation speed, which is characterized in that an incident optical fiber bundle is mounted at the front end of an adjustable slit, the incident end of a collimating lens group is mounted at the rear end of the adjustable slit, and a high-nick-number grating and a triangular prism are mounted in a mechanical fixing structure. The high-nick grating is located on the optical axis of the collimating lens group, the prism is located between the high-nick grating and the long-focal-length convergent lens group, the photoelectric conversion device is connected to the other end of the long-focal-length convergent lens group, and the data output end of the photoelectric conversion device is electrically connected with the data acquisition and analysis system; according to the invention, the instrument broadening of the system is limited by setting the adjustable slit, an
