FOLDED LENS SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18407043 titled 'FOLDED LENS SYSTEM
Simplified Explanation:
The patent application describes a folded lens system that includes lenses with refractive power and two light folding elements such as prisms. The system redirects light through multiple axes to improve focusing capabilities.
- The system includes lenses with refractive power and light folding elements.
- Light is refracted through multiple axes to improve focusing.
- The system may include a front aperture and a sensor for autofocusing.
- The lens system has a low F-number and a 35 mm equivalent focal length in the medium to long telephoto range.
Key Features and Innovation:
- Includes lenses with refractive power and light folding elements.
- Redirects light through multiple axes for improved focusing.
- Allows for autofocusing with a sensor or optical actuators.
- Low F-number and medium to long telephoto range focal length.
Potential Applications:
- Photography equipment
- Surveillance systems
- Medical imaging devices
Problems Solved:
- Improved focusing capabilities
- Autofocusing functionality
- Compact design for various applications

Original Abstract Submitted
A folded lens system that includes lenses with refractive power and two light folding elements such as prisms. A first lens on a first axis refracts light to a first folding element. The first folding element redirects the light from the first axis onto a second axis on which one or more lenses are arranged. The lenses on the second axis refract the light to a second folding element. The second folding element redirects the light onto a third axis on which a sensor is disposed. The lens system may include a front aperture. The sensor may be moved on the third axis to provide autofocusing, or alternatively the lens system may include one or more optical actuators that provide autofocusing. The lens system may have a low F-number (<=2.8), and may have a 35 mm equivalent focal length in the medium to long telephoto range.
