US 2026/0227600 A1 · OPTICAL SYSTEM AND CAMERA MODULE

Abstract

An optical system, according to the present embodiment, comprises first to eighth lenses disposed along the optical axis, wherein the first lens has negative (−) 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, the sixth lens has positive (+) refractive power, the seventh lens has negative (−) refractive power, and the eighth lens has positive (+) refractive power. An aperture is disposed between the fourth lens and the fifth lens, and the distance between the first lens and the second lens is the largest among the distances between the adjacent lenses on the optical axis.
