Abstract
The invention relates to the development of economical camera modules having objectives contained therein with a minimal constructional length and excellent optical properties. It is made possible as a result that camera modules of this type can be used in mobile telephones or minicomputers, such as PDAs (personal digital assistant).

- 31. A camera module having a miniaturized objective with a support structure including at least one of quartz glass and borosilicate glass having an IR barrier filter, on the visual field side, applied by wafer technology and comprising a dielectric layer system and an image-producing optoelectronic unit, on the image field side, applied by wafer technology and at least one monolithic aspherical optical lens made of a polymer material, the support structure being glued to the at least one lens without an air gap.
- 51. A method for producing camera modules on a wafer scale, the camera modules having a miniaturized objective, the method including providing a support structure including at least one of quartz glass and borosilicate glass, providing on the support structure an IR barrier filter on the visual field side by wafer technology, providing a dielectric layer system and an image-producing optoelectronic unit on the image field side by wafer technology, providing at least one monolithic aspherical optical lens of a polymer material, and gluing the support structure to the at least one lens without an air gap, providing said image-producing optoelectronic unit on the image field side of the camera modules by wafer technology comprises applying said image-producing optoelectronic unit on a support structure comprising at least one of quartz glass and borosilicate glass by wafer technology, providing an IR barrier filter comprising applying a dielectric layer system on the support structure by wafer technology, producing at least one polymer lens plate by at least one of hot stamping and UV replication, connecting said at least one polymer lens plate to the IR barrier filter by at least one of a UV curable adhesive and a thermally curable adhesive on the visual field side without an air gap and separating the individual camera modules using saw blades.
