Embodiment Construction

[0053] Preferred embodiments of the present invention will be described below with reference to the drawings.

[0054] [Wafer lens, wafer lens aggregate, wafer lens laminate]

[0055] Such as figure 1 As shown, the wafer lens laminate 1 has a structure in which wafer lens aggregates 2 and 4 are stacked up and down, and the wafer lens aggregate 2 and the wafer lens aggregate 4 are bonded with an adhesive 27 .

[0056] The wafer lens aggregate 2 includes: a wafer lens 10 ; and a glass spacer 14 for maintaining a certain distance from the wafer lens 20 .

[0057] The wafer lens 10 includes: a circular glass substrate 11; and resin portions 12, 13 formed on the upper and lower surfaces of the glass substrate 11, respectively.

[0058] A resin portion 12 is formed on the upper surface of the glass substrate 11 . The resin portion 12 includes: convex lens portions 12a constituting an optical surface; and non-lens portions 12b formed between the convex lens portions 12a.

Abstract

Disclosed is a method for producing a wafer lens, wherein misalignment between a glass substrate and a molding mold is suppressed from occurring. The method for producing a wafer lens comprises: a step wherein, in a first reduced pressure atmosphere, an energy-curable resin is arranged between a glass substrate (11) and a molding mold, and the glass substrate (11) is pressed against the molding mold, while sucking the glass substrate (11) and affixing the molding mold; a step wherein, in a second reduced pressure atmosphere that is under a higher pressure than the first reduced pressure atmosphere, the arrangement of the glass substrate (11) and the molding mold is adjusted while sucking the glass substrate (11) and affixing the molding mold; and a step wherein the energy-curable resin is cured by applying energy to the energy-curable resin, and the glass substrate (11) is released from the molding mold.

Description

technical field [0001] The present invention relates to a manufacturing method of a wafer lens, a manufacturing method of a wafer lens aggregate, a manufacturing method of a wafer lens laminate, a wafer lens manufacturing apparatus, a wafer lens aggregate manufacturing apparatus, and a wafer lens laminate manufacturing apparatus. Background technique [0002] In the field of optical lens production, a technique for obtaining a highly heat-resistant optical lens by providing a lens portion made of a curable resin on a glass substrate has been studied (see, for example, Patent Document 1). As an example of a method of manufacturing an optical lens to which this technology is applied, a method has been proposed in which a plurality of lens parts made of curable resin are formed on the surface of a glass substrate to form a so-called "wafer lens", and then cut for each lens part. Glass base board. [0003] An example of a method of manufacturing a wafer lens when a photocurable...
