The spectrometer is a basic equipment used for analyzing the structures and compositions of substances. The structural design of a miniature optical fiber spectrometer with the symmetrical Czerny-Turner layout is introduced in detail in this paper. The spectrometer has a compact structure without an active mechanism and can be assembled and used easily. The test results of the spectrometers optical performances are also given. The instrumental ground test and the environmental tests show that the spectrometer has high stability and satisfies the requirements of design.
