Document Type and Number:
WIPO Patent Application WO/2024/054093
Kind Code:
A1
Abstract:
An optical system according to an embodiment of the present invention comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, which are sequentially arranged from an object side to an image side, wherein the first lens has positive refractive power, the second lens has negative refractive power, the third lens has positive refractive power, the fourth lens has negative refractive power, the fifth lens has positive refractive power, and the sixth lens has negative refractive power. The object-side surface of the sixth lens is concave toward the object side; the image-side surface of the fifth lens is convex toward the image side; the object-side surface of the fifth lens and the image-side surface of the sixth lens include a critical point at which the tilt angle is 0; and the object-side surface of the sixth lens has the largest tilt angle in the range of 0.8 to 1.2 times the vertical distance from the optical axis to the critical point of the image-side surface of the sixth lens.
