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

This abstract first appeared for US patent application 20240288675 titled 'ZOOM LENS AND IMAGE CAPTURING APPARATUS

The abstract describes a zoom lens (ZL) consisting of a first lens unit with positive refractive power, a second lens unit with negative refractive power, a third lens unit with positive refractive power, an n-1th lens unit, and an nth lens unit, arranged from object side to image side. The n-1th and nth lens units are positioned on the image side relative to an aperture stop.

  • First lens unit with positive refractive power
  • Second lens unit with negative refractive power
  • Third lens unit with positive refractive power
  • Arrangement of lens units from object side to image side
  • N-1th and nth lens units located on the image side with respect to aperture stop

Potential Applications: - Photography lenses - Microscopes - Telescopes

Problems Solved: - Improving image quality - Enhancing zoom capabilities

Benefits: - Clearer and sharper images - Increased zoom range

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

Questions about Zoom Lens Technology: 1. How does the arrangement of lens units affect image quality in a zoom lens? 2. What are the advantages of having lens units with different refractive powers in a zoom lens?
