Display 200902948 Deleted as a liquid crystal display, cathode ray tube display or other display device. The image sensor 1082 receives an image of a laser passing through an optical system composed of the to-be-detected lens and displays it on the display 1 to 84. The general inspector judges the inter-plane eccentricity value of the lens 200 to be inspected based on the image displayed on the display surface. The so-called inter-plane eccentricity value refers to the distance between the center of the optical axis of one aspherical surface and the center of the optical axis of another aspherical surface in the double-sided aspherical mirror. The greater the eccentricity between the faces, the worse the quality of the double-sided aspherical mirror. The eccentricity value of the to-be-detected lens 200 is determined based on the image displayed on the display 1 to 84: 1) If the image displayed on the display 1 〇 84 is a clear concentric circle, as shown in FIG. 3, the corresponding The eccentricity of the lens 2 is less than 5 microns; 2) If the image displayed on the display 1〇84 is a concentric circle with slight flare and blur, as shown in Figure 4, the corresponding lens 2 The eccentricity value is less than 10 micrometers; 3) if the image displayed on the display 1084 is a non-concentric circle, such as a "goldfish eye" type non-concentric circle, as shown in FIG. 5, the corresponding eccentricity value of the lens 200 is greater than 12 Micron. The lens corresponding to the first two cases belongs to the good product, and the lens corresponding to the latter case belongs to the defective product. Referring to FIG. 6, a second embodiment of the present invention provides a lens eccentricity detecting method. The method comprises the steps of: (100a) emitting a laser; (200a) moving the lens to be inspected to the optical path of the laser and fixing the lens to be detected on the optical path of the laser; and (300a) receiving the laser passing through the lens to be inspected It is caused to form an image and display the image, and the eccentricity value of the lens to be detected is determined based on the displayed image. In the step (100a), the laser emitting device 102 emits a laser light, preferably 200902948, and the emitted lightning beam size is 〇.1 μm. In step (200a), the missing part of the lens carrying device 1〇4 loses the optical line 3GQ, and the moving part drives the missing part and the optical system 300 to move horizontally and/or vertically to be detected. Lens · Located on the light path of the laser. 5 Image Image Sensor of Image Processing Device 108 In step (300a), 1082 receives an image of the laser passing through the optical system consisting of the lens to be detected and displays it on the display. The general inspector determines the eccentricity value of the to-be-detected lens 2 according to the image displayed on the display 1084: If the image displayed on the display is a clear concentric circle, as shown in FIG. 3, the corresponding The eccentricity value of the lens 200 is less than 5 micrometers; 2) the image displayed on the display is a concentric circle with slight facial spots and blur, as shown in Fig. 4, the corresponding eccentricity value of the lens 200 is less than 1〇. Micron; 3) If the image displayed on the brain of the display is a non-concentric circle of the non-concentric "%" goldfish eye type, as shown in Figure 5, the corresponding eccentricity of the lens 200 is greater than 12 microns. The first two cases correspond to the mirror # belongs to H - the lens corresponding to the case is a defective product. In the lens eccentricity detecting system 100 and the detecting method of the embodiment, the eccentric value of the surface of the lens 2 to be detected is determined by the image which is not displayed on the display 1084, and the eccentricity of the lens 200 can be accurately displayed. Quality management, simple operation, no need for professional inspectors, and can be imported into the mass production process. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application in accordance with the law. However, the above description is only the preferred embodiment of the present invention, and those skilled in the art will be able to include the equivalent modifications or variations of the invention in the spirit of the invention.
