    摘要： The imaging lens consists of, in order from the object side, a first lens group, an aperture stop, a second lens group having a positive refractive power. During focusing from a distant object to a close-range object, the first lens group remains stationary, and the aperture stop and the second lens group integrally move to the object side. The imaging lens satisfies predetermined conditional expressions relating to a focal length of the whole system, a focal length of the first lens group, a principal point position of the second lens group, a focal length of the second lens group, a back focal length, and the like.

    摘要： An imaging lens is provided in which a total angle of view is 150 degrees or more, and which exhibits a high-image quality, is compact, is inexpensive, and keeps a stable quality under a harsh environment in an on-board camera or the like.An imaging lens includes a first lens having a negative refracting power and having a meniscus shape in which a convex surface is directed toward an object side; a second lens having a negative refracting power and having a meniscus shape in which a convex surface is directed toward the object side; a third lens having a positive refracting power and having bi-convex shape; an aperture stop; a fourth lens having a positive refracting power and having a bi-convex shape; a fifth lens having a negative refracting power and having a bi-concave shape; and a sixth lens having a positive refracting power and having a bi-convex shape, the first lens, the second lens, the third lens, the aperture stop, the fourth lens, the fifth lens, and the sixth lens being arranged in order from the object side to an image surface side. Thus, the imaging lens includes six groups and six sheets of independent lenses as a whole, has a total angle of view of 150 degrees or more, and fulfills predetermined conditional expressions.

    摘要： An endoscope objective optical system includes an optical-path deflecting prism group and a lens group. A visual-field direction of the endoscope objective optical system is variable by moving a prism in the optical-path deflecting prism group. The optical-path deflecting prism group includes, in order from an object side, a first prism, a second prism, and a third prism, which are disposed to be in mutual proximity. The visual-field direction is variable to a first direction by the first prism undergoing a rotational movement with respect to the second prism, and the visual-field direction is variable to a second direction which differs from the first direction, by the first prism and the second prism undergoing rotational movement integrally with respect to the third prism.

    摘要： An optical image capturing system comprising, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element. The first lens element with negative refractive power has a concave image-side surface. The second lens element, the third lens element and the fourth lens element have refractive power. The fifth lens element has refractive power. The sixth lens element with refractive power has an image-side surface being concave in a paraxial region and includes at least one convex shape in an off-axial region, wherein the surfaces thereof are aspheric. The seventh lens element with refractive power has an image-side surface being concave in a paraxial region and includes at least one convex shape in an off-axial region, wherein the surfaces thereof are aspheric.
