Description

   Optical image lens and plastic material, image taking device and electronic device   

The present invention relates to an optical imaging lens and an imaging device, and more particularly to a miniaturized optical imaging lens and an imaging device having an optical lens capable of absorbing long-wavelength light and applicable to an electronic device.

General mobile products are nothing more than using a Photocoupled Device (CCD) or a Complementary Metal-Oxide Semiconductor Sensor (CMOS Sensor) as an electronic photoreceptor to capture images for imaging. However, the electronic photosensitive element can not only receive and respond to visible light, but also sense infrared light that is not visible to the human eye. If infrared light is not filtered out during photography, it will cause image color distortion and make the photos taken and the human eye real. There are obvious differences.

In order to solve this problem, the conventional technology is to set an infrared filter between the lens and the electronic photosensitive element to filter out the infrared light. However, the additional infrared filter has a certain thickness and increases the thickness of the optical lens. The number of components not only makes it difficult to reduce the size of the lens, but also makes it difficult to mount it on a miniaturized mobile device.

In order to improve the filtering effect of infrared light, a blue glass filter has also been developed. Although it can also provide the filtering effect of infrared light, it has to extend the lens due to its absorption elimination mechanism to strengthen the effect of the thickness of the filter. Back focal length is more detrimental to lens miniaturization.

In addition, in recent years, the requirements for the specifications of mobile product lenses have been increasing, and the current market has become increasingly thinner and higher imaging quality. To improve the imaging quality, more combinations of optical lenses are required to effectively correct aberrations. Lenses with at least five optical lenses have become mainstream. Although lenses with multiple optical lenses have high imaging quality, they are not easy to shrink due to the large number of optical lenses, and often the problem that the lens obviously protrudes the product surface is not only affected. The thinness of mobile products also hinders its aesthetic design, highlighting the importance of streamlining the internal components of the lens.

Therefore, how to improve the technology of filtering out infrared light so that it can filter out infrared light so as to avoid image color distortion and facilitate the miniaturization of the lens, thereby conforming to the trend of thinning mobile products, and conducive to the application of multi-optical lenses In order to reduce the number of components used, it helps meet the requirements of thinning and high imaging quality, which has become the goal of related industry players.

An object of the present invention is to provide an optical imaging lens including at least one optical lens, and at least one of the optical lenses includes at least one long-wavelength absorbing component, thereby facilitating absorption of long-wavelength light and preventing long-wavelength light from being electronically photosensitive. The problem of color shift caused by the component receiving causes the image to be close to the color seen by the human eye. In addition, since at least one optical lens in the optical image lens has the ability to absorb long-wavelength light, the optical image lens does not need to be equipped with an additional infrared filter, so it is beneficial to reduce the number of components in the optical image lens and make the optical The image lens achieves a more miniaturized effect, which is conducive to being mounted on electronic products that require thinning, and is beneficial to lenses with multiple optical lenses to meet the requirements of thinning and high imaging quality. In addition, the long-wavelength absorbing component of the present invention is uniformly mixed in the plastic material of the optical lens, and it does not give the optical lens the ability to absorb long-wavelength light through the lens coating technology, so it can avoid the high manufacturing cost and technology of the lens coating technology The lack of excessive difficulty can reduce costs and improve manufacturing yield.
