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

In describing the present invention below, terms referring to the components of the present invention are named in consideration of the functions of each component, so they should not be understood as limiting the technical components of the present invention.

In addition, throughout the specification, that a component is 'connected' to another component includes not only the case where these components are 'directly connected', but also the case where they are '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 somewhat exaggerated for description. In addition, the spherical or aspheric shape of the lens described and shown in the detailed description or drawings is only presented as an example and is not limited to the shape of the lens.

In this specification, the numerical values for the radius of curvature, thickness, distance, and effective aperture radius of the lens are all units of mm, and units of angles are degrees.

An effective aperture radius means a 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 optical portion of the lens.

Description of the shape of the lens in this specification means the shape of the paraxial region of the lens. For example, the fact that the object side surface of the first lens is convex means that the paraxial portion of the object side surface of the first lens is convex. Therefore, even if the object side of the lens is described as being convex, not all of the object side of the lens is convex. For example, even when it is described that the image side surface of the first lens is concave, the edge of the image side surface of the first lens may be convex. For reference, the paraxial region described above means a region including an optical axis.

An imaging optical 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 the 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 image sensor.

A lens of an imaging optical system includes an optical portion and a rib. The optical portion of the lens is a portion that substantially refracts light. The optical part of such a lens is generally formed in the center of the lens. The rib of the lens is a part that enables alignment between the lenses. The ribs of these lenses extend from the optical portion in the radial direction. The optics of the lenses may not be in contact with each other. For example, the first to seventh lenses are arranged at predetermined intervals along the optical axis. The ribs of the lenses may optionally contact. For example, the first to fourth lenses, the first to fifth lenses, or the second to fourth lenses may make contact between ribs 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 disposed 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 image surface and blocks infrared rays included in light incident on the image surface.

The imaging optical system may further include a diaphragm and a spacer. The diaphragm is disposed in front of the first lens or between the lenses to adjust the amount of light incident on the image surface. A spacer is disposed between the lenses to maintain a constant distance between the lenses. In addition, the spacer is made of a light blocking material and can block unnecessary light penetrating into the rib side of the lens. There may be 6 or more spacers. For example, the first spacer is disposed between the first and second lenses, the second spacer is disposed between the second and third lenses, and the third spacer is disposed between the third and fourth lenses. The fourth spacer is disposed between the fourth and fifth lenses, the fifth spacer is disposed between the fifth and sixth lenses, and the sixth spacer is disposed between the sixth and seventh lenses. Additionally, a seventh spacer disposed between the seventh lens and the filter may be further included.

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 or both surfaces are concave. For example, the object side of the second lens may have a convex shape. As another example, both surfaces of the second lens may be concave. The second lens includes an aspheric surface. For example, one surface or both surfaces of the second lens may be aspheric.

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

For example, an object side surface or an image side surface of the fifth lens may have a concave shape. The fifth lens includes an aspheric surface. For example, one surface or both surfaces of the fifth lens may be aspheric.

The sixth lens has refractive power. For example, the sixth lens may have positive or negative refractive power. The sixth 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 sixth lens. Accordingly, at least one surface of the sixth lens may have a different shape of the paraxial portion and the shape of the peripheral portion. For example, the paraxial portion of the sixth lens may be concave, but the edge portion may be convex. The sixth lens includes an aspheric surface. For example, one surface or both surfaces of the sixth lens may be aspheric.

The seventh lens has refractive power. For example, the seventh lens may have positive or negative refractive power. The seventh lens has a concave shape on one surface. For example, an image side surface 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 different shape of the paraxial portion and the shape of the peripheral portion. For example, the paraxial portion of the seventh lens may be concave, but the edge portion may be convex. The seventh lens includes an aspherical surface. For example, one surface or both surfaces of the seventh lens may be aspheric.

A lens of an imaging optical system is made of a light material having 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.

For example, it is advantageous to improve chromatic aberration when the distance between the first and second lenses is shorter than the distance between the third and fourth lenses.

For example, an imaging optical system that does not satisfy at least one of Conditional Expressions 29 to 31 may have a longer overall length due to the refractive power of lenses disposed behind the diaphragm.
