に開示され℃いる。At this time, single pieces of glass are ground one by one. Because of the polishing process, it is not possible to obtain the desired smoothness, and in the case of glass-based annual leave, there are "sink marks" and "warps" caused by heat shrinkage during molding.
Lenses with good IK could not be obtained, and the practical application of aspherical lenses was delayed. For this reason, a method of obtaining an aspherical lens with a high density by adding plastic TSM to a spherical glass lens is disclosed in Japanese Patent Application Laid-Open No. 1JFL 5? - It is disclosed in No. 12412.

。Sometimes, when a lens blank is made of plastic, it is difficult to optically align the axis of the lens blank and mechanically align the axis of the lens based on the outer diameter of the lens due to the poor surface area and outer diameter dimensions of the lens blank. The purpose of the present invention is to improve the above-mentioned drawbacks and to provide a composite lens with high precision in which the lens blank and thin film can be assembled.

金型および賦形方法は第1の実施例と同体である。In FIG. 5, the convex portion of the flange is formed by processing aluminum in advance and incorporating it into the lens blank by insert molding. (Cb) is a front view, and Cb is a cross section taken along line X--X of (Cb). 9 is an aluminum convex portion. The shaping mold and shaping method for the four films are the same as in the first embodiment.

It is also possible to use the convex part 5 of the collar 2 as shown in .The advantage of this case is that the JlliH
When changing #, the advantage is that only the convex portion 5 needs to be reworked. Furthermore, in the case of the aluminum convex portion explained in the example of 5g5, since the convex portion has a high shape area, it is expected that the interpolation will be even more effective.

S= J−β
となる。The degree of centering of the lens surface according to the invention depends on the formation and arrangement of the rod-shaped protrusions provided on the flange. That is, the misalignment 1tS shown in FIG. 10 becomes S=J-β, where α and β are the deformation amounts of the bar-shaped convex portion.

The rod-shaped convex portion of rLWL was deformed by 5 μm. As a result, the centering thickness was 6 μm, which is different from the conventional centering deviation '
It was possible to significantly reduce the width of i50 μm.

耐久性の同上化を図ることができた。Figure 7 (α) is a sectional view of the main part of the compound lens of the present invention installed in the sash. 10 is a tfilli made of glass fiber cambered polycarbonate, and 11 is an aluminum spacer. A gap B of 50 μm is provided between the outer circumference of the brim and the inner circumference of m'r410. This is because the material of the composite lens is Aku+)lLt@shield, and is it a jump material? The sharp part due to fM expansion difference and the complex lens brim are ring J.
This is to prevent the lens from deforming due to stress due to contact due to llJf formation. The center alignment of the compound lens with respect to the orientation is achieved by providing the spacer 11 with a recess similar to the sleeve described above.Furthermore, as shown in FIG. 7(b), the compound lens If the bar-shaped convex part is made of aluminum, this bar-shaped convex part will align the compound lens in the original axial direction +
By determining the position relative to 01 and 11, and by making the other brim surfaces and the spacer surface not in contact with each other, it was possible to improve the durability of the assembled lens.
