Embodiment Construction

[0022] The lens for a digital camera of the present invention is used for a small digital camera, or portable electronic devices such as a mobile phone with a digital camera, and a PDA.

[0023] Please refer to figure 1 As shown, the lens 1 for a digital camera of the present invention includes a lens base 10 and a filter film 20 . Wherein the lens base 10 is an ordinary spherical lens or aspheric lens for digital cameras, and its material is transparent bodies such as glass or plastics, and the filter film 20 is attached to the lens base 10 by hot pressing, which can be an anti-reflection film, Infrared cut filter film, etc.

[0024] Please also refer to figure 2 , image 3 , Figure 4 and Figure 5 As shown, the manufacturing method of the digital camera lens 1 comprises the following steps:

[0025] Coating a uniform water-soluble UV-curable adhesive 31 on the glass substrate 30;

[0026] Place the glass substrate 30 coated with UV-curable glue 31 in a vacuum evapo...

Abstract

The present invention provides a kind of lens for digital camera. The lens includes lens body and filtering film, the lens body is one common lens for digital camera, and the filtering film is attached to the lens body through hot pressing. The making process of the lens for digital camera includes coating ultraviolet cured glue, evaporation coating one layer of planar filtering film onto the surface of the ultraviolet cured glue, irradiating with ultraviolet ray to separate the planar filtering film from the glass base, hot pressing the planar filtering film onto the lens body and other steps.

Description

【Technical field】 [0001] The invention relates to an optical lens, in particular to a lens for a digital camera and a manufacturing method thereof. 【Background technique】 [0002] In the structure of a lens module of a digital camera, there are generally a lens group, a filter, an image sensor, and the like. Among them, the lens group is used for digital camera imaging, and generally consists of one to several lens sheets. In order to increase the light transmittance or wear resistance of the lens sheet, a layer of thin film is often evaporated on the surface of the lens sheet. Filters are used to isolate specific infrared light or ultraviolet light to prevent the image sensor from receiving and generating noise. Usually there are anti-reflection (AR coating) filters and infrared cut-off (IR-CUT coating) filters. Filters are mainly It is cut with a diamond tool or a grinding wheel after coating on a glass plate. As the size of the digital camera lens module continues to de...
