Hundred-million-pixel turning lens with precision improving function and using method thereof

Abstract

The invention relates to the technical field of high-precision test equipment, and in particular to a hundred-million-pixel turning lens with a precision improving function and a using method thereof.The turning lens comprises a first unit lens module group and a second unit lens module group; the right end face of the first unit lens module is fixedly connected with a second unit lens module; the right end face of the second unit lens module is fixedly connected with a third unit lens module; the right end face of the third unit lens module is fixedly connected with a flexible joint sleeve;and the right side of the lower end face of the third unit lens module is fixedly connected with a supporting block. In the present invention, a first unit fixing frame, a first unit spiral ring, a rubber pad, a single lens and a total reflection lens are arranged, so that the appearance length of the product is shortened, the installation space of equipment can be saved. In order to guarantee high precision is guaranteed, an arranged supporting block guarantees that the right side of the supporting block is in contact with a camera in a connecting process of the right side of the third unit fixing frame and the camera, and therefore a supporting effect is achieved.

Description

technical field [0001] The invention relates to the technical field of high-precision testing equipment, in particular to a 100-million-pixel turning lens with a function of improving precision and a method for using the same. Background technique [0002] In the application of high-precision test equipment, high-precision industrial telecentric lenses must be used. The existing equipment not only requires high precision, but also requires a small volume. The previous telecentric lenses are generally large in size, and the imaging accuracy is not so high. , the large size will contradict the limited equipment space, better lenses and lenses with higher finish should be used in the design, in order to ensure the effect of megapixels, high refraction lenses should be considered in the design, and in the The length of the product was considered during the design, the refracting lens used should have high reflectivity, and how to eliminate the light spot should be considered.

[0003] Because the large-diameter telecentric lenses currently on the market are generally large in size, long in size, and require a large installation space, which is not conducive to saving equipment installation space. In addition, it supports industrial cameras with tens of millions of pixels, which can support billions of Pixel-level lenses are basically abroad, and there are few styles, so these restrict the manufacture of this lens to a certain extent, and various unknown risks in actual production.
