Embodiment Construction

[0033] Embodiments of compact lens systems (which may also be referred to as lens systems) are described herein, which may include one or more refractive lens elements (referred to as lens stacks). Embodiments of the compact lens system can be used in cameras with a small package size (referred to as small format factor cameras). Embodiments of small format factor cameras are described herein, including but not limited to implementations of photosensors and compact lens systems.

[0034] Conventionally, lens systems for small form factor cameras include lens stacks consisting of two or more refractive lens elements. Each lens element in the lens stack can include an active optical area and a flange area, and can be formed from a transparent optical plastic or glass material. For example, the lens elements may be injection molded optical plastics. While one or more of the lens elements may be formed from transparent optical materials having different optical properties (e.g.,...

Abstract

Light-absorbing flange lenses that may be used in the lens stacks of compact lens systems. In a light-absorbing flange lens, the effective area of the lens is composed of a transparent optical material, and at least a portion of the flange of the lens is composed of an optical material that absorbs at least a portion of the light that enters the flange. Using light-absorbing flange lenses may allow the lens barrel to be eliminated from the lens system, thus reducing the X-Y dimensions of the lens system when compared to conventional compact lens systems that include a lens stack enclosed in a lens barrel. In addition, using a light-absorbing material in the flanges of the light-absorbing flange lenses may reduce or eliminate optical aberrations such as lens flare, haze, and ghosting in images.

Description

Background technique [0001] Related technical description [0002] The advent of small mobile multipurpose devices such as smartphones and tablet computers or tablet devices has led to the need for high resolution small form factor cameras integrated in the devices. However, due to the limitations of conventional camera technology, conventional small cameras used in such devices tend to capture image. Achieving high resolution in a camera with a small package size usually requires the use of a photosensor with a small pixel size and a better compact imaging lens system. Technological advances have enabled reductions in the pixel size of photosensors. However, as photosensors have become more compact and powerful, the demand for compact imaging lens systems with improved imaging quality performance has increased. Contents of the invention [0003] Embodiments of the present disclosure may provide a small package size camera (referred to as a small format factor camera). ...
