摘要： Provided is a small-sized five-element image pickup lens which ensures a sufficient lens speed of about F2 and exhibits various aberrations being excellently corrected. The image pickup lens is composed of, in order from the object side, a first lens with a positive refractive power, including a convex surface facing the object side; a second lens with a negative refractive power, including a concave surface facing the image side; a third lens with a positive or negative refractive power; a fourth lens with a positive refractive power, including a convex surface facing the image side; and a fifth lens with a negative refractive power, including a concave surface facing the image side. The image-side surface of the fifth lens has an aspheric shape, and includes an inflection point at a position excluding an intersection point with the optical axis.

摘要： An objective lens relating to the present invention includes a first optical path difference providing structure in which a first basic structure and a second basic structure are overlapped with each other. The first basic structure is a blaze-type structure which emits a Xth-order diffracted light flux, when the first light flux passes through the first basic structure, where the value of X is an odd integer. At least a part of the first basic structure arranged around an optical axis includes a step facing an opposite direction to the optical axis. The second basic structure is a blaze-type structure which emits a Lth-order diffracted light flux, when the first light flux passes through the second basic structure, where the value of L is an even integer. At least a part of the second basic structure arranged around the optical axis includes a step facing the optical axis.

摘要： An image pickup lens includes: an aperture stop; a first lens having a positive power and including a convex surface facing an object side; a second lens having a negative power and including a concave surface facing an image side; a third lens in a meniscus shape having a positive power and including a convex surface facing the image side; and a fourth lens in a meniscus shape having a negative power and including a convex surface facing the object side. The image pickup lens satisfies predetermined conditions relating to a composite focal length of the first through third lenses, a length of an air space between the third lens and the fourth lens along the optical axis, and a curvature radius of a surface of the second lens facing the image side.
