Description

   Optical imaging lens, image capturing device and electronic device   

The present invention relates to an optical imaging lens and an image capturing device, and more particularly, to a miniaturized optical imaging lens and an image capturing device including a plastic optical lens capable of absorbing light of a limited wavelength and applicable to electronic devices.

Existing color image sensing elements can simultaneously respond to visible light, long-wavelength red light with a wavelength of 650nm to 700nm, and infrared light with a wavelength of 700nm to 1100nm, thus causing poor color saturation and image color distortion.

Conventional technology provides a blue glass filter (infrared light absorption plate) to provide infrared light filtering effect, but it is costly and limited by the type of material and cannot sufficiently filter infrared light. In addition, light-absorbing filters need to have a large thickness, which leads to an increase in back focus. In the current market, multi-lens lenses are the mainstream, which makes it difficult to miniaturize high-quality imaging lenses.

Furthermore, in order to meet the needs of miniaturization, aspheric manufacturing and mass production, high-quality multi-lens lenses are made of plastic materials, but plastic optical lenses cannot avoid short-wavelength light such as ultraviolet light or blue light damage and deterioration , Resulting in reduced durability and imaging quality. Although conventional coating technology can reflect ultraviolet light, the coating cost is high and there are problems with uniformity.

The optical imaging lens, image pickup device and electronic device provided by the present invention are provided with a limited-wavelength absorption optical lens. The limited-wavelength absorption optical lens can select a combination of long-wavelength, short-wavelength and specific narrow-wavelength absorption components, and can borrow Different absorption components and content configurations are added to the plastic optical lens to meet the absorption effect in a specific wavelength range, and effectively filter out long-wavelength red, infrared, ultraviolet, blue, or specific-range wavelength light to avoid color misregistration Problems, reducing the number of components, miniaturization, reducing manufacturing costs, reducing technical difficulties, improving manufacturing yield, improving durability, improving imaging quality, improving color contrast, and reducing non-dominant wavelength light interference.
