[0002] Spectrometer is also called spectrometer, and the most widely known one is direct reading spectrometer. It is a device that measures the intensity of different wavelength positions of spectral lines with photodetectors such as photomultiplier tubes. It consists of an entrance slit, a dispersion system, an imaging system and one or more exit slits. The electromagnetic radiation of the radiation source is separated into the required wavelength or wavelength region by the dispersion element, and the intensity is measured at the selected wavelength (or scanning a certain band).

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] like Figure 1-5As shown, a spectrometer that is easy to replace the light source includes a main housing 30 and an upper housing 20, the upper housing 20 is fixedly mounted on the main housing 30, a cover assembly 10 is mounted on the upper housing 20, the cover assembly 10 is connected to the upper housing 20 through a connector 112, and a lamp chamber 40 is provided in the main housing 30 at a position opposite to the cover assembly 10; the cover assembly 10 includes a cover 11 and a liquid crystal bracket 12, the liquid crystal bracket 12 is fixed on the cover 11, a cover fixing hole 114 is provided on the cover 11, and the cover 11 is fixed to the upper housing 20 through the cover fixing hole 114. Among them, the liquid crystal bracket 12 is used to carry a liquid crystal device, such as a liquid crystal display, etc. An internal thread can be provided in the cover fixing hole 114, so that it can be fixed by screws. The connector 112 can be a rotating shaft.

[0025] In order to firmly fix the liquid crystal bracket 12 on the cover plate 11, a bracket fixing hole 113 is opened on the cover plate 11, and the liquid crystal bracket 12 is fixed on the cover plate 11 through the bracket fixing hole 113. Figure 4 As shown, the liquid crystal bracket 12 forms an integral body after being mounted on the cover plate 11. This integral body is then mounted on the upper housing 20, so that the liquid crystal bracket 12 is securely placed in the spectrometer.

[0026] In order to better replace the lamp in the lamp chamber 40, the size of the cover plate 11 is larger than the size of the lamp chamber 40. In this way, when the cover plate 11 is opened, the operator will have sufficient space to replace the lamp.

[0027] The cover plate 11 is provided with a display window 111, and the bracket fixing hole 113 is provided at the outer edge of the display window 111. The liquid crystal display screen on the liquid crystal bracket 12 can be displayed in the display window 111.

[0028] Preferably, there are four bracket fixing holes 113, and the four bracket fixing holes 113 are centrally symmetrically distributed around the center of the display window 111. The use of four bracket fixing holes 113 can make the liquid crystal bracket 12 more firmly fixed on the cover plate 11. The liquid crystal bracket 12 can be fixed to the cover plate 11 by common fasteners such as screws or latches. The screws or latches are inserted into the bracket fixing holes 113 to achieve fixation.

[0029] After the cover plate 11 is covered on the upper shell 20, the cover plate 11 needs to be fixed in position to prevent the cover plate 11 from moving during use. Therefore, the cover plate 11 preferably has two fixing holes, and the two cover plate fixing holes 114 are symmetrically distributed near the edge of the cover plate.

[0030] In order to make it easier to open the cover plate 11 when replacing the light source, a handle 115 is further provided on the cover plate 11 . The handle 115 is located at a side away from the display window 111 .
