[0030] In some embodiments of the present invention, Figure 1 As shown, the light splitting module 400 further includes a focusing lens 510 , and the focusing lens 510 is disposed at the coaxial output end 440 .

[0033] Specifically, the first beam splitter 460, the second beam splitter 470 and the third beam splitter 480 are arranged in the base shell 450. By setting the relative positions of the first beam splitter 460, the second beam splitter 470, the third beam splitter 480, the laser incident end 410, the visible light output end 420, the infrared output end 430 and the coaxial output end 440, the first beam splitter 460, the second beam splitter 470 and the third beam splitter 480 are parallel to each other, the incident angle of the laser with the third reflection surface is approximately 45°, the laser is reflected from the third emission surface and irradiated to the second transmission surface, the incident angle of the laser with the second transmission surface is approximately 45°, after passing through the second beam splitter 470, it is emitted from the second reflection surface, and then irradiated on the first reflection surface, the incident angle of the laser with the first reflection surface is approximately 45°, and after being reflected by the first reflection surface, the laser is finally emitted from the coaxial output end 440.

[0034] Visible light enters from the coaxial output end 440 and illuminates the first reflection surface. The incident angle of the visible light to the first reflection surface is approximately 45°. After being reflected by the first reflection surface, the visible light illuminates the second reflection surface.

The incident angle of the infrared ray and the second reflection surface is approximately 45°. The infrared ray passes through the first beam splitter 460 from the first reflection surface, then is emitted from the first transmission surface, and finally is output from the infrared output end 430 .

[0036] In some embodiments of the present invention, the first beam splitter 460 is a first filter, which can reflect visible light and laser light and allow infrared light to pass through.

[0037] The first filter can allow light of a certain wavelength band to pass through and reflect light of other wavelength bands. Specifically, the first filter can be made of colored glass, acrylic, resin and other materials. The first filter filters out and reflects visible light and laser, and allows infrared light to pass through.

[0038] In some embodiments of the present invention, the second beam splitter 470 is a second filter, which can reflect visible light and allow laser light to pass through.

[0039] Similarly, the second beam splitter 470 also allows light of a certain wavelength band to pass through and reflects light of other wavelength bands, and may also be made of colored glass, acrylic, resin and other materials. Specifically, the second beam splitter 470 reflects visible light and allows laser to pass through.

[0040] It should be noted that the spectrometer module 400 can also adopt other forms of spectrometer combinations to change the reflection and transmission of light of different wavelengths, thereby appropriately changing the relative position settings of the first spectrometer 460, the second spectrometer 470, the third spectrometer 480, the laser incident end 410, the visible light output end 420, the infrared output end 430 and the coaxial output end 440, which is also within the concept of this solution.

[0045] In some embodiments of the present invention, the light splitting module 400 includes an infrared collimating lens 540 , and the infrared collimating lens 540 is disposed at the infrared emitting end 430 .

[0046] The focusing lens 510 is usually a convex lens, which converges the laser output from the coaxial output end 440. The infrared rays entering the spectrometer module 400 through the focusing lens 510 form parallel infrared rays. The infrared collimating lens 540 can converge the infrared rays and then enter the infrared temperature measurement module 300.

[0048] It should be noted that the frequency and wavelength of infrared rays correspond to different temperatures. In order to improve the accuracy of temperature measurement, two infrared temperature measuring components with different sensitivities to infrared wavelength ranges are selected. Among them, the first infrared temperature measuring component 310 has a higher sensitivity to infrared rays with lower frequency and longer wavelength. Infrared rays in this wavelength range usually correspond to low temperature areas, while the second infrared temperature measuring component 320 has a higher sensitivity to infrared rays with higher frequency and shorter wavelength. Infrared rays in this wavelength range usually correspond to high temperature areas, thereby improving the temperature measurement range that can be detected by infrared temperature measurement and ensuring good accuracy.

[0049] The processing module 600 is connected to the first infrared temperature measuring element 310 and the second infrared temperature measuring element 320 respectively. The processing module 600 can obtain the temperature signals collected by the first infrared temperature measuring element 310 and the second infrared temperature measuring element 320 respectively, and select appropriate temperature signals at different temperatures to present to the user.

[0050] Specifically, the wavelength splitter 330 can also allow light of a certain wavelength band to pass through and reflect light of other wavelength bands. Specifically, the wavelength splitter 330 can be made of materials such as colored glass, acrylic, and resin.
