Difference between Cardinal point (optics) and Focal length

Cardinal point (optics) vs. Focal length

In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. The focal length of an optical system is a measure of how strongly the system converges or diverges light.

Similarities between Cardinal point (optics) and Focal length

Cardinal point (optics) and Focal length have 9 things in common (in Unionpedia): Focus (optics), Image, Magnification, Photography, Pinhole camera model, Radius of curvature (optics), Ray (optics), Refractive index, Thin lens.

Focus (optics)

In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge.

Image

An image (from imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.

Magnification

Magnification is the process of enlarging the appearance, not physical size, of something.

Photography

Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.

Pinhole camera model

The pinhole camera model describes the mathematical relationship between the coordinates of a point in three-dimensional space and its projection onto the image plane of an ideal pinhole camera, where the camera aperture is described as a point and no lenses are used to focus light.

Radius of curvature (optics)

Radius of curvature (ROC) has specific meaning and sign convention in optical design.

Ray (optics)

In optics a ray is an idealized model of light, obtained by choosing a line that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.

Refractive index

In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how light propagates through that medium.

Thin lens

In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces.
