Description of the Invention: [Technical Field of the Invention] The present invention relates to a method of manufacturing a coated lens. [Prior Art] With the development of optical products, the application range of optical lenses is becoming wider and wider. Accordingly, the industry employs a variety of methods to fabricate optical lenses to accommodate the market demand for different specifications of optical lenses (see "Fabrication of Diffractive Optical Lens for Beam splitting Using LIGA Process 55, Mechatronics and Automation, Proceedings of the 2006 IEEE International Conference on 5 Pp.1242-1247, 2006.06). However, optical lenses produced by various methods in batches can be applied to optical equipment after subsequent processing. For example, lenses manufactured by injection molding technology need to be machined by cutting, throwing, etc. Processing and cutting the waste edge to improve the lens fineness. 'After physically or chemically, the surface of the optical lens is coated with a single or multi-layer film, and the interference generated by the incident, reflected and transmitted light on the film layer interface is used to achieve focusing and collimation. Effects of filtering, reflection, and refraction. The existing coated lens is manufactured as shown in Figs. 1 to 3, and provides a tray device. The tray device includes a lower tray 10 and an upper tray 20. The lower tray 10 is provided with plural Through holes 12 arranged in an array, the lower tray 10 A positioning post 14 is protruded from the corner. The diameter of the through hole 12 gradually decreases from top to bottom, and the longitudinal section thereof is inverted trapezoidal. The upper tray 2 is similar in shape and size to the lower tray 10. The disk 2 is also provided with a plurality of through holes 22 arranged in an array. The diameter of the through holes 22 gradually changes from top to bottom in 200914864. The longitudinal section is trapezoidal. The through hole 22 of the upper tray 20 and the lower tray The through holes 12 of 10 correspond to each other and have the same size. The four corners of the upper tray 2 are provided with positioning holes matching the positioning posts 14 of the lower tray 10. 24. Each lens to be plated 30 is placed The upper tray 12 is inserted into the through hole 12, and then the upper tray 20 is covered to pass the positioning post 14 through the corresponding positioning hole 24. Thus, each lens 30 to be plated is clamped and positioned on the lower tray 1〇. The through hole 12 is interposed between the through hole 12 and the through hole 22 of the upper tray 20. The tray device holding the mirror 51 is then placed in a coating device for coating. When the film is coated, the lens 30 to be plated is passed through the through hole. The inner surface of 12, 22 is carried. Since the longitudinal section of the through holes 12 and 22 is trapezoidal, the coated area cannot be completely covered. The lens 30 is coated, and the edge of the lens to be plated 3, that is, the inner surface of the lens 30 to be plated close to the through holes 12, 22 cannot be coated with a film, so that the film thickness distribution is uneven. When the light passes through these When there is no area of the money film, it will cause reflection, which will result in poor image quality. The traditional solution is to increase the size of the lens so that the value of the uneven distribution is limited to the optical area and the effective area. Today, lenses need to find other solutions. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a method of fabricating a lens having a uniform thickness.
