[0026] The outside of the body 1 is fixedly connected with two long plates 12, the inside of the two long plates 12 is fixedly connected with a shell 13 on one side, the inside of the two shells 13 is fixedly connected with a spring 14, the outside of the two springs 14 is fixedly connected with a column 15 at the outer end, the outside of the two columns 15 is fixedly connected with a light emitter 18, the light emitter 18 is fixedly connected with a soft pad one 16 on one side, the soft pad one 16 is fixedly connected with a guide pad 17 at the top, the light emitter 18 is embedded with a coupling lens in the inside, the light emitter 18 is in the same plane with the deuterium lamp tube 5.

[0027] The inside of the body 1 is provided with a hole groove on one side, the outside of the body 1 is fixedly connected with a soft pad two 20 on one side, the soft pad two 20 is located outside the hole groove and is in the same plane, which can facilitate the connection and protection work of the soft pad two 20.

[0028] The guide pad 17 is provided in an arc shape, the soft pad one 16 is in the same plane with the light emitter 18, the light emitter 18 is hollow in the middle, which can facilitate the protection and clamping work of the soft pad one 16 to the optical filter.

[0030] In the specific implementation process, such as Figures 1-4As shown, when the experiment of spectral measurement is needed, first, the staff needs to turn on the deuterium lamp switch 7, which will make the deuterium lamp tube 5 be powered on through the deuterium lamp power supply 26, and then the tungsten lamp switch and the regulator 8 are rotated to be turned on, which will make the tungsten lamp tube 3 be lit, and the light source inside the tungsten lamp tube 3 will be concentrated through the light collecting tube 4. At this time, since the deuterium lamp tube 5 is in the lit state, when the light source of the tungsten lamp tube 3 is collected through the light collecting tube 4, it will form a combined light source with the deuterium lamp tube 5, and then it is emitted through the coupling lens inside the light emitter 18, so as to realize that the deuterium lamp light and the tungsten lamp light are integrated through the lens and then fused into one light emitting port for emission, which meets the light source demand of wide spectrum from deep ultraviolet to near infrared.

[0031] When the heat inside the machine body 1 needs to be dissipated, the staff needs to turn on the switch, and then the air inlet fan 11 will supplement the external air into the machine body 1, and the air outlet fan 10 will discharge the air again, so as to achieve the heat dissipation effect of the machine body 1.

[0032] In the experiment of spectral measurement, since different thicknesses of the filter are needed, when the staff picks up the filter through the tool, it can be inserted between the guide pad 17 and the soft pad two 20, and in this process, when the filter outside contacts the guide pad 17, it will be guided and protected by the arc of the guide pad 17, so as to prevent scratching and damage, and when the filter sinks to contact the soft pad one 16 on one side, the other side of the filter will also contact the soft pad two 20 at the same time, and as the filter continuously moves downward, the soft pad one 16 and the soft pad two 20 will clean the two sides of the filter outside, so as to achieve the effect of pre-cleaning the surface of the filter.

[0033] In the above working process, since the filter separates the soft pad one 16 and the soft pad two 20 by its thickness, when the soft pad one 16 is squeezed and moved, it will simultaneously drive the light emitter 18 to move, and the light emitter 18 will simultaneously drive the column 15 to move and the spring 14 to stretch during the movement, so as to adapt to different thicknesses and different wavebands of the filter for experiment, prevent the device from being difficult to adapt to different thicknesses of the mirror body and the mirror body from being easily tilted and falling, and ensure the high adaptability and stability of the filter.

[0037] In the specific implementation process, as shown in Figure 4 and Figure 5 When the staff needs to take out or replace the filter, the staff needs to rotate the rod body 25 downward, and the rod body 25 will synchronously drive the folding plate 24 to rotate in the process of rotation, the folding plate 24 will drive the strip plate 22 and the guide plate 23 to rotate, and the guide plate 23 will synchronously drive the clamping plate 19, the light outlet 18 and the soft pad 16 to move at the same time in the process of rotation, and the soft pad 16 will synchronously drive the column body 15 to move and the spring 14 to stretch in the process of movement, so that the space outside the filter can be enlarged, the filter can be quickly taken out, and the practicability of the device is ensured.
