Abstract
A fisheye lens assembly and an electronic apparatus are disclosed. The fisheye lens has an angle of view of 150° or more, includes a plurality of lenses including an aspherical lens having an inflection point on one surface or both surfaces thereof, and satisfies the expression 35 μm≤SAG_MAX, where SAG_MAX denotes a maximum value of absolute values of SAG values of inflection points of the aspherical lens.
Claims12
A fisheye lens assembly comprising:
- a plurality of lenses sequentially arranged from an object side to an image sensor side and having an angle of view of 150° or more,
- wherein the plurality of lenses comprise an aspherical lens having an inflection point on one surface or both surfaces thereof,
- wherein the aspherical lens is located closest to the image sensor side among the plurality of lenses and satisfies the expressions below:
- 35 μm≤SAG_MAX,
- 1.4≤Nd≤1.7, and
- 10≤Abv≤60,
- where SAG_MAX denotes a maximum value of absolute values of SAG values of inflection points of the aspherical lens, Nd denotes a refractive index, and Abv denotes an Abbe number,
- wherein the plurality of lenses further comprise a front group, an iris, and a rear group, sequentially arranged from the object side to the image sensor side,
- wherein the front group sequentially comprises, from the object side, a first lens having negative refractive power and a second lens having negative refractive power, and
- wherein the rear group comprises the aspherical lens.
