  2. Cardinal point (optics) - Wikipedia

    en.wikipedia.org/wiki/Cardinal_point_(optics)

    The optical center of a spherical lens is a point such that if a ray passes through it, the ray's path after leaving the lens will be parallel to its path before it entered. In the figure at right, [ 8 ] the points A and B are where parallel lines of radii of curvature R 1 and R 2 meet the lens surfaces.

  3. Diaphragm (optics) - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_(optics)

    The centre of the diaphragm's aperture coincides with the optical axis of the lens system. Most modern cameras use a type of adjustable diaphragm known as an iris diaphragm, and often referred to simply as an iris. See the articles on aperture and f-number for the photographic effect and system of quantification of varying the opening in the ...

  4. Epipolar geometry - Wikipedia

    en.wikipedia.org/wiki/Epipolar_geometry

    Since the optical centers of the cameras lenses are distinct, each center projects onto a distinct point into the other camera's image plane. These two image points, denoted by e L and e R, are called epipoles or epipolar points. Both epipoles e L and e R in their respective image planes and both optical centers O L and O R lie on a single 3D ...

  5. Camera lens - Wikipedia

    en.wikipedia.org/wiki/Camera_lens

    Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.

  6. Entrance pupil - Wikipedia

    en.wikipedia.org/wiki/Entrance_pupil

    Increasing the focal length of a lens (i.e., zooming in) will usually cause the f-number to increase, and the entrance pupil location to move further back along the optical axis. The center of the entrance pupil is the vertex of a camera's angle of view [3] and consequently its center of perspective, perspective point, view point, projection ...

  7. Optical axis - Wikipedia

    en.wikipedia.org/wiki/Optical_axis

    An optical axis is an imaginary line that passes through the geometrical center of an optical system such as a camera lens, microscope or telescopic sight. [1] Lens elements often have rotational symmetry about the axis. The optical axis defines the path along which light propagates through the system, up to first approximation.
