DETAILED DESCRIPTION

[0023] The above and other technical features and advantages of the utility model are further described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only preferred embodiments of the utility model, not all of them.

[0024] Example:

[0025] like Figure 1-Figure 3 As shown, the utility model provides an optical system device, which includes a beam splitter tube 1, an objective lens seat 2 is installed below the beam splitter tube 1, and a plurality of objective lenses 3 are connected to the end of the objective lens seat 2, a total reflection adjustment seat 4 is installed on one side of the beam splitter tube 1, a light source processing lens tube 5 is installed at the end of the total reflection adjustment seat 4, and an LED light source 6 is installed at the end of the light source processing lens tube 5;

[0026] The LED light source 6 emits cold white light, which is processed by the light source processing lens barrel 5 and enters the LED light source 6. The processed cold white light enters the spectroscope barrel 1 under the reflection of the total reflection adjustment seat 4. The spectroscope barrel 1 separates the incident light and irradiates it downward. The light irradiated downward is converged by the objective lens 3 and then projected.

[0027] An eyepiece tube 7 is installed at the top of the spectroscope tube 1, and a main camera 8 is installed at the end of the eyepiece tube 7. The light is projected after being converged by the objective lens 3, and the projected light is reflected into the main camera 8, which collects images.

[0028] An observation window is provided on one side of the eyepiece barrel 7 , and a secondary camera 9 is connected to the observation window. The secondary camera 9 collects and images the reflected light from the side of the spectroscopic barrel 1 .

[0029] The total reflection adjustment seat 4 includes an adjustment seat housing 41 and a total reflection mirror 42;

[0030] The adjustment seat housing 41 is connected to one side of the spectroscope tube 1, a total reflection mirror 42 is installed inside the adjustment seat housing 41, a light source entrance port is provided at the top of the adjustment seat housing 41, a light source exit port is provided at one side of the adjustment seat housing 41, and the total reflection mirror 42 corresponds to both the light source entrance port and the light source exit port;

[0031] The LED light source 6 emits cold light when in operation. The cold light passes through the light source processing lens barrel 5 and enters the adjustment seat housing 41 through the light source incident port of the adjustment seat housing 41 and irradiates the surface of the total reflection mirror 42. The total reflection mirror 42 deflects the incident light and reflects it out. The reflected light enters the spectroscope barrel 1 from the light source outlet of the adjustment seat housing 41.

[0032] The total reflection adjustment seat 4 also includes a laser generator 43;

[0033] The laser generator 43 is disposed in the middle of one side of the total reflection mirror 42. The laser generator 43 can emit blue light. The emitted blue light passes through the total reflection mirror 42 and directly enters the spectroscope tube 1. The spectroscope tube 1 separates the test light and irradiates it downward. The light irradiated downward is converged by the objective lens 3 and then projected.

[0034] The total reflection adjustment seat 4 also includes a straightening mirror 44;

[0035] The straightening mirror 44 is installed at the light source outlet on one side of the adjustment seat housing 41. The center of the straightening mirror 44 and the total reflection mirror 42 are on the same axis. After the total reflection mirror 42 deflects the incident light and reflects it, the reflected light is irradiated to the surface of the straightening mirror 44. The light is refracted by the straightening mirror 44 and then emitted at a horizontal angle.

[0036] The light source processing lens barrel 5 comprises a processing lens barrel body 51, a condenser lens 52, a filter 53 and a frosted glass sheet 54;

[0037] The end of the processing lens barrel body 51 is connected to the light source incident port of the adjustment seat housing 41, and the condenser 52 is installed at the middle position inside the processing lens barrel body 51.

The center of the condenser 52 and the center of the total reflection mirror 42 are on the same axis.

[0038] The light emitted by the LED light source 6 is filtered by the filter 53 and then converged by the condenser 52 to irradiate the surface of the frosted glass 54 . The frosted glass 54 scatters the light and then the light enters the total reflection adjustment seat 4 .

[0039] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
