Hereinafter, a preferred embodiment of the present invention will be described in detail based on the accompanying illustrative drawings.

In describing the present invention below, terms referring to the components of the present invention are named in consideration of the function of each component, and thus should not be construed as limiting the technical components of the present invention.

In addition, throughout the specification, that a component is 'connected' with another component includes not only cases where these components are 'directly connected' but also 'indirectly connected' through other components. means that In addition, 'including' a certain component means that other components may be further included, rather than excluding other components, unless otherwise stated.

In addition, the thickness, size, and shape of the lenses shown in the drawings are exaggerated for explanation. In addition, the spherical or aspherical shape of the lens described and illustrated in the detailed description or drawings is only presented as an example and is not limited to the shape of the lens.

In the present specification, all numerical values for the radius of curvature, thickness, distance, and effective aperture radius of the lens are in mm, and the unit of angle is Degree.

The effective aperture radius refers to the radius of one surface (object-side surface and image-side surface) of each lens through which light actually passes. Thus, the effective radius may be the same size as the radius of the optics of the lens.

In this specification, the description of the shape of the lens means the shape of the paraxial region of the lens. For example, that the object side of the first lens is convex means that the paraxial portion of the object side of the first lens is convex. Therefore, although it is described that the object side of the lens is convex, the entire object side of the lens is not convex. For example, even when it is described that the image side of the first lens has a concave shape, the image side edge of the first lens may have a convex shape. For reference, the paraxial region described above means a region including the optical axis.

An optical imaging system according to an embodiment of the present invention may include a plurality of lenses disposed along an optical axis. For example, the imaging optical system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially arranged from an optical axis. Here, the first lens means a lens closest to the object (or subject), and the seventh lens means a lens closest to the image surface or the image sensor.

The lens of the imaging optical system includes an optical unit and a rib. The optical part of the lens is a part that substantially refracts light. The optical portion of such a lens is generally formed in the center of the lens. The ribs of the lenses are the parts that allow alignment between the lenses. The ribs of these lenses are formed to extend radially from the optical unit. The optics of the lenses may not contact each other. For example, the first to seventh lenses are disposed at predetermined intervals along the optical axis. The ribs of the lenses may selectively contact. For example, the ribs of the first to fourth lenses, the first to fifth lenses, or the second to fourth lenses may be in contact with each other to facilitate optical axis alignment.

Next, the configuration of the imaging optical system will be described.

The imaging optical system may include a plurality of lenses. For example, the imaging optical system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially arranged from the object side.

The imaging optical system may further include an image sensor and a filter. The image sensor forms an image surface and converts light refracted by the first to seventh lenses into electrical signals. The filter is disposed between the lens and the upper surface, and blocks infrared rays including light incident on the upper surface.

The imaging optical system may further include an aperture and a spacer. The diaphragm is disposed in front of the first lens or between the lens and the lens to adjust the amount of light incident on the image surface. The spacer is disposed between the lens and the lens to maintain a constant distance between the lenses. In addition, the spacer may be made of a light-shielding material to block unnecessary light penetrating into the rib side of the lens. There may be six or more spacers. For example, the first spacer is disposed between the first lens and the second lens, the second spacer is disposed between the second lens and the third lens, and the third spacer is disposed between the third lens and the fourth lens. The fourth spacer is disposed between the fourth lens and the fifth lens, the fifth spacer is disposed between the fifth lens and the sixth lens, and the sixth spacer is disposed between the sixth lens and the seventh lens. Additionally, it may further include a seventh spacer disposed between the seventh lens and the filter.

Next, a lens constituting the imaging optical system will be described.

The first lens has refractive power. For example, the first lens may have positive or negative refractive power. One surface of the first lens is convex. For example, the object side of the first lens may have a convex shape. The first lens includes an aspherical surface. For example, one or both surfaces of the first lens may be aspherical.

The second lens has refractive power. For example, the second lens may have positive or negative refractive power. At least one surface of the second lens is convex. For example, the object side of the second lens may have a convex shape. The second lens includes an aspherical surface. For example, one or both surfaces of the second lens may be aspherical.

The third lens has refractive power. For example, the third lens may have positive or negative refractive power. The third lens has a convex surface. For example, the object side or the image side of the third lens may have a convex shape. The third lens includes an aspherical surface. For example, one or both surfaces of the third lens may be aspherical.

The fourth lens has refractive power. For example, the fourth lens may have positive or negative refractive power. The fourth lens has a convex surface. For example, the object side or the image side of the fourth lens may have a convex shape. The fourth lens includes an aspherical surface. For example, one or both surfaces of the fourth lens may be aspherical.

The fifth lens has refractive power. For example, the fifth lens may have positive or negative refractive power. The fifth lens has a concave surface. For example, the object side or the image side of the fifth lens may have a concave shape. The fifth lens includes an aspherical surface. For example, one or both surfaces of the fifth lens may be aspherical.

The sixth lens has refractive power. For example, the sixth lens may have positive or negative refractive power. The sixth lens has an inflection point. For example, an inflection point may be formed on at least one of the object side and the image side of the sixth lens. Accordingly, the shape of the paraxial portion and the shape of the peripheral portion of at least one surface of the sixth lens may be different from each other. For example, the paraxial portion of the sixth lens may have a concave shape, but the edge portion may have a convex shape. The sixth lens includes an aspherical surface. For example, one or both surfaces of the sixth lens may be aspherical.

The seventh lens has refractive power. For example, the seventh lens may have positive or negative refractive power. The seventh lens has a concave surface. For example, the image side of the seventh lens may have a concave shape. The seventh lens has a shape having an inflection point. For example, an inflection point may be formed on at least one of the object side and the image side of the seventh lens. Accordingly, at least one surface of the seventh lens may have a shape different from the shape of the paraxial part and the shape of the peripheral part. For example, the paraxial portion of the seventh lens may have a concave shape, but the edge portion may have a convex shape. The seventh lens includes an aspherical surface. For example, one or both surfaces of the seventh lens may be aspherical.

The lens of the imaging optical system is made of a light material with high light transmittance. For example, the first to seventh lenses may be made of a plastic material. However, the material of the first to seventh lenses is not limited to plastic.

The aspherical surfaces of the first to seventh lenses may be expressed by Equation (1).

In Equation 1, c is the curvature of the lens (the reciprocal of the radius of curvature), K is the conic constant, Y is the distance from any point on the aspherical surface of the lens to the optical axis, and the constants A to H are aspherical constants . And Z (or SAG) represents the distance in the optical axis direction from any point on the aspherical surface of the lens to the vertex of the aspherical surface.

Conditional Equation 20 provides a thickness range of the first lens for realizing a compact imaging optical system. For example, the first lens having a thickness that exceeds the upper and lower limits of Conditional Expression 20 is too thick or too thin to be manufactured.

Conditional Expression 22 provides design conditions for the first to fourth lenses for improving chromatic aberration. For example, it is advantageous to improve chromatic aberration when the distance between the first lens and the second lens is shorter than the distance between the third lens and the fourth lens.

Conditional expressions 25 to 28 are design conditions for realizing a compact imaging optical system. For example, lenses outside the numerical range of Conditional Expressions 26 or 28 are difficult to inject and process.

Conditional Expressions 29 to 31 provide design conditions for the imaging optical system in consideration of the position of the diaphragm. For example, the optical imaging system that does not satisfy one or more of the conditional expressions 29 to 31 may have an overall length due to the refractive power of lenses disposed behind the diaphragm.

59 and 60 are combined cross-sectional views of the imaging optical system and the lens barrel. The imaging optical system 100 described herein includes a self-aligning structure. For example, as shown in FIG. 59 , the optical imaging system 100 includes a structure in which optical axes of four lenses 1000 , 2000 , 3000 , and 4000 are aligned by mutual coupling. Here, the first lens 1000 disposed closest to the object side is in contact with the lens barrel 200 so that the optical axes are aligned, and the second lens 2000 to the fourth lens 4000 are the lenses ( The optical axis is aligned with the first to third lenses). Here, the second lens 2000 to the fourth lens 4000 do not contact the inner surface of the lens barrel. For reference, although the first lens 1000 to the fourth lens 4000 are shown to be coupled to each other in FIG. 59, the second lens to the fifth lens or the third lens is in a range in which four consecutive lenses are coupled to each other. to the sixth lens or the fourth to seventh lenses may be changed.

As another example, as shown in FIG. 60 , the optical imaging system 100 includes a structure in which optical axes of five lenses 1000 , 2000 , 3000 , 4000 and 5000 are aligned by mutual coupling. Here, the first lens 1000 disposed closest to the object side is in contact with the lens barrel 200 so that the optical axes are aligned, and the second lens 2000 to the fifth lens 5000 are the lenses ( The optical axis is aligned with the first to fourth lenses). Here, the second lens 2000 to the fifth lens 5000 do not contact the inner surface of the lens barrel. For reference, although the first lens 1000 to the fifth lens 5000 are shown to be coupled to each other in FIG. 60 , the second lens to the sixth lens or the third lens is in a range in which five consecutive lenses are coupled to each other. to the seventh lens.

The rib shape of the lens will be described in detail with reference to FIG. 62 .

The lens of the imaging optical system described herein includes a structure for preventing flare and reflection. For example, the rib regions of the first to seventh lenses 1000, 2000, 3000, 4000, 5000, 6000, and 7000 constituting the imaging optical system may be partially surface-treated as illustrated in FIG. 62 . The method of surface treatment may include chemical etching, physical grinding, and the like.

The surface treatment area EA may be formed entirely from the edge of the effective surface of the lens to the end of the rib. However, as shown in FIG. 62 , the untreated area NEA including the concave portions E11 , E21 , and E22 may not be surface treated or may have a different roughness (roughness) from the surface treatment area EA. . The size G1 of the first unprocessed area formed on one surface of the lens may be different from the size G2 of the second unprocessed area formed on the other surface of the lens. For example, G1 may be greater than G2.

G1 has a size including the first concave portion E11, the second concave portion E21, and the third concave portion E22, and G2 is the second concave portion E21 and the third concave portion E22. It may have a size that includes The distance G4 from the end of the rib to the second concave portion E21 may be smaller than the distance G3 from the end of the rib to the first concave portion E11 . Similarly, the distance G5 from the end of the rib to the third concave portion E22 may be smaller than the distance G3 from the end of the rib to the first concave portion E11 .
