ZOOM LENS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18544536 titled 'ZOOM LENS AND IMAGE PICKUP APPARATUS

The abstract of the patent application describes a zoom lens with a first lens unit, a second lens unit, and an aperture stop, where the distance between lens units changes during zooming. The first lens unit consists of at least three or four lens elements, satisfying predetermined inequalities.

  • The zoom lens includes a first lens unit with negative refractive power.
  • It also has a second lens unit with positive refractive power.
  • The distance between adjacent lens units changes during zooming.
  • The first lens unit comprises at least three or four lens elements.
  • Specific predetermined inequalities are met in the design.

Potential Applications: - Photography equipment - Surveillance systems - Medical imaging devices

Problems Solved: - Improved zoom capabilities - Enhanced image quality - Versatile lens design

Benefits: - Clearer and sharper images - Greater flexibility in capturing different scenes - Enhanced overall performance of the lens

Commercial Applications: Title: Advanced Zoom Lens Technology for Enhanced Imaging This technology can be used in professional cameras, security cameras, and medical imaging devices, offering superior zoom capabilities and image quality.

Questions about Zoom Lens Technology: 1. How does the design of the first lens unit contribute to the overall performance of the zoom lens? 2. What advantages does the variable distance between lens units offer in terms of zooming capabilities and image quality?

Frequently Updated Research: Ongoing research focuses on optimizing the design of the lens elements to further enhance image resolution and clarity.


Original Abstract Submitted

A zoom lens includes, in order from an object side to an image side, a first lens unit having negative refractive power, a second lens unit having positive refractive power, and an aperture stop. A distance between adjacent lens units changes during zooming. The first lens unit includes at least three or four lens elements. Predetermined inequalities are satisfied.
