OPTICAL SYSTEM AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18305433 titled 'OPTICAL SYSTEM AND IMAGE PICKUP APPARATUS

Simplified Explanation

The patent application describes an optical system that includes a glass optical element with negative refractive power. This element is positioned either on the object side or the image side of the intersection of the optical axis and a pupil paraxial ray. The optical element meets a specific condition.

  • The optical system includes a glass optical element with negative refractive power.
  • The optical element is positioned on either the object side or the image side of the intersection of the optical axis and a pupil paraxial ray.
  • The optical element is made of a glass material.
  • The optical element satisfies a predetermined condition.


Original Abstract Submitted

An optical system includes an optical element having negative refractive power and disposed on at least one of an object side and an image side of an intersection of an optical axis and a pupil paraxial ray. The optical element is made of a glass material and satisfies a predetermined condition.
