LENS ASSEMBLY AND ELECTRONIC DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17992051 titled 'LENS ASSEMBLY AND ELECTRONIC DEVICE INCLUDING THE SAME

Simplified Explanation

The patent application describes a lens assembly with seven lenses arranged from an object side to an image sensor side. The assembly includes a first lens with negative refractive power, a second lens with positive refractive power and at least one aspherical surface, and a third lens with positive refractive power. The refractive index of the second or third lens is 1.6 or higher, and the seventh lens has a refractive index of 1.6 or higher. The lens assembly has a half-field angle of 50 degrees or more.

  • Lens assembly with seven lenses arranged from object side to image sensor side
  • First lens has negative refractive power and concave object side surface and convex image sensor side surface
  • Second lens has positive refractive power and at least one aspherical surface
  • Third lens has positive refractive power
  • Refractive index of second or third lens is 1.6 or higher
  • Refractive index of seventh lens is 1.6 or higher
  • Lens assembly has a half-field angle of 50 degrees or more

Potential Applications

  • Camera lenses
  • Microscope lenses
  • Telescope lenses

Problems Solved

  • Improved image quality
  • Enhanced optical performance
  • Increased field of view

Benefits

  • Higher refractive index lenses for improved performance
  • Aspherical surfaces for better image quality
  • Wide field of view for capturing more in the frame


Original Abstract Submitted

According to an embodiment of the present disclosure, a lens assembly may include at least seven lenses sequentially arranged from an object side to an image sensor side, where a first lens may have negative refractive power and may include a concave object side surface and a convex image sensor side surface, a second lens may have positive refractive power and may include an object side surface and an image sensor side surface at least one of which is aspherical, a third lens may have positive refractive power, one of the second lens and the third lens may have a refractive index of 1.6 or more, the refractive index of the seventh lens disposed seventh from the side may be 1.6 or more, and the lens assembly may have a half-field angle of 50 degrees or more. Various other embodiments are possible.
