Abstract
An optical imaging system includes four or more lenses disposed in order from an object side. Among the lenses, a frontmost lens disposed to be closest to an object side has two or more reflective surfaces. Among the lenses, a rearmost lens disposed to be closest to an image side has an inflection point formed on at least one of an object-side surface and an image-side surface.
Claims16
An optical imaging system comprising:
- four or more lenses disposed in order from an object side,
- wherein among the lenses, a frontmost lens disposed to be closest to an object side has two or more reflective surfaces, and
- wherein among the lenses, a rearmost lens disposed to be closest to an image side has an inflection point formed on at least one of an object-side surface and an image-side surface.
An optical imaging system comprising:
- a first lens, a second lens having negative refractive power, a third lens, and a fourth lens, disposed in order from an object side,
- wherein the first lens has a first reflective surface, configured to reflect light incident from an object-side surface of the first lens, and a second reflective surface configured to reflect the light, reflected by the first reflective surface, to an image-side surface of the first lens.
