Title:
OPTICAL SYSTEM AND CAMERA MODULE
Document Type and Number:
WIPO Patent Application WO/2024/049284
Kind Code:
A1
Abstract:
An optical system disclosed in an embodiment of the invention may comprise a first lens to a seventh lens aligned along an optical axis from an object side toward a sensor side. The first lens may have negative refractive power. The combined refractive power of the third to seventh lenses may be positive. The first lens has a meniscus shape that is convex from an optical axis toward the sensor side. The center thickness of the first lens may be greater than the center thickness of each of the second to seventh lenses. The first to seventh lenses may include multiple spherical lenses and multiple aspherical lenses. Each of the spherical lenses may have an object-side surface and a spherical sensor-side surface that are spherical. Each of the aspherical lenses may have an object-side surface and a sensor-side surface that are aspherical. At least one of the multiple aspherical lenses may be made of a different material from the spherical lenses.
