In a typical lens barrel, lenses are assembled in a lens barrel in a direct stacking manner. In fact, the dimension design of each lens in the lens is limited by the factors of processing or measurement, and is not as accurate as the initial design, so that the actual dimension after completion has errors. And errors in the spacing between the lenses may cause curvature of field in the end product. Generally, the actual size of the lens is controlled within an allowable variation range, and the allowable variation amount is called a size tolerance. When the lens barrel is assembled, if the lens barrel is assembled by direct stacking, the dimensional tolerance of the lens thickness is accumulated, which results in serious Field Curvature (Field Curvature) of the image projected through the lens and poor optical quality. In order to improve the above problems, it is common practice to increase the process accuracy and reduce the lens tolerance, but reducing the lens tolerance requirement will result in additional manufacturing cost.
Patent publication No. CN110471155A discloses a lens and a method for manufacturing the same, including: a first structure comprising a first set of first lenses and a first set of second lenses adjacent to each other, the first set of first lenses having a thickness D1 in an optical axis direction, the first set of first lenses being spaced apart from the first set of second lenses in the optical axis direction by a distance D2, if the thickness D1 changes by one unit, the amount of change in the distance of the focal point of the lens at the off-axis position is S1, and the distance D2 changes by one unit, the amount of change in the distance of the focal point of the lens at the off-axis position is S2, and | S2/S1| <2, and the first set of second lenses being separated from the first set of first lenses by a first bearing surface; and a second structure comprising a second group of first lenses and a second group of second lenses which are adjacent to each other, wherein the thickness of the second group of first lenses in the optical axis direction is D3, the distance from the second group of first lenses in the optical axis direction to the second group of second lenses is D4, if the thickness of D3 changes by one unit, the variation of the distance of the focal point of the lens at the off-axis position is S3, and when the distance of D4 changes by one unit, the variation of the distance of the focal point of the lens at the off-axis position is S4, and | S4/S3| ≧ 2, and the second group of first lenses are separated from the second group of second lenses by a first spacer.

In the attaching process, the lens films on different transparent substrates are not easy to be accurately aligned, so that the optical quality of the wafer level lens cut by the lens sheet is poor;
3. the molding accuracy of the lens thickness of the glass lens is more than the molding accuracy of the thickness of the plastic lens controlled to have an error of several micrometers by an error of several tens micrometers, so that it is difficult to obtain a high molding accuracy. Therefore, it is difficult to achieve desired optical performance, and in particular, it is difficult to suppress focus shift.
