LENS APPARATUS AND IMAGING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18439587 titled 'LENS APPARATUS AND IMAGING APPARATUS
The lens apparatus described in the patent application consists of a holding frame for a lens, a driving unit to move the holding frame along the optical axis, and a mount to attach the apparatus to an imaging device.
- The driving unit is partially located inside a circumscribed circle of the non-circular lens shape when viewed along the optical axis.
- Part of the lens overlaps with the object-side end surface of the mount or is closer to the image plane than the object-side end surface of the mount along the optical axis.
Potential Applications: This lens apparatus could be used in various imaging devices such as cameras, microscopes, or telescopes to enhance focusing capabilities and image quality.
Problems Solved: The apparatus addresses the challenge of precise lens movement and alignment within imaging systems, improving overall performance and image clarity.
Benefits: Improved focusing accuracy, enhanced image quality, and increased versatility in imaging applications.
Commercial Applications: This technology could be valuable in the photography, medical imaging, and scientific research industries, where precise lens control is essential for high-quality results.
Questions about Lens Apparatus: 1. How does the placement of the driving unit inside the lens apparatus impact its performance? 2. What are the potential challenges in integrating this lens apparatus into existing imaging systems?
Frequently Updated Research: Ongoing research in lens design and optical engineering may lead to further advancements in lens apparatus technology, improving functionality and performance.
Original Abstract Submitted
A lens apparatus includes a holding frame configured to hold a first lens, a driving unit configured to drive the holding frame in a direction along an optical axis, and a mount configured to mount the lens apparatus on an imaging apparatus. When the lens apparatus is viewed from the direction along the optical axis, at least a part of the driving unit is disposed inside a circumscribed circle of the first lens having a non-circular shape. A part of the first lens is disposed at a location that overlaps an object-side end surface of the mount or is disposed closer to an image plane than the object-side end surface of the mount in the direction along the optical axis.
