Imaging lens system with wide field of view and high image quality
A recently filed patent (Publication Number: US20230314771A1) describes an imaging lens system consisting of eight lens elements arranged in a specific order along an optical path. Each lens element has an object-side surface facing the object side and an image-side surface facing the image side. The patent claims various conditions that must be satisfied for the lens system to function optimally.
One of the key conditions is that the object-side surface of the third lens element must be concave in a paraxial region. Additionally, the curvature radii of certain lens elements, such as the second lens element and the fourth lens element, must meet specific ratios. The axial distances between lens elements and the central thicknesses of certain lens elements also need to satisfy certain requirements.
The patent also describes the imaging lens system's compatibility with other components. For example, it can be used in an image capturing unit that includes an image sensor placed on the image surface of the lens system. Furthermore, the lens system can be incorporated into an electronic device.
Another embodiment of the imaging lens system includes a fifth lens element with negative refractive power and a sixth lens element with positive refractive power. Similar to the previous embodiment, this system has specific conditions that must be met regarding the curvature radii, axial distances, and central thicknesses of the lens elements.
The patent also mentions the inclusion of an aperture stop between certain lens elements and provides additional conditions for the curvature radii, central thicknesses, and refractive indices of the lens elements.
Overall, the patent describes specific configurations and conditions for an imaging lens system consisting of eight lens elements. These configurations and conditions aim to optimize the performance of the lens system in capturing high-quality images.
