Telecentric lens

Index Telecentric lens

A telecentric lens is a compound lens that has its entrance or exit pupil at infinity; in the prior case, this produces an orthographic view of the subject. [1]

Color filter array

In photography, a color filter array (CFA), or color filter mosaic (CFM), is a mosaic of tiny color filters placed over the pixel sensors of an image sensor to capture color information.

Colorimetry is "the science and technology used to quantify and describe physically the human color perception." It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.

In electronics, crosstalk is any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel.

Defocus aberration

In optics, defocus is the aberration in which an image is simply out of focus.

Digital single-lens reflex camera

A digital single-lens reflex camera (also called digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.

Entocentric lens

An entocentric lens is a compound lens which has its entrance or exit pupil inside the lens.

Entrance pupil

In an optical system, the entrance pupil is the optical image of the physical aperture stop, as 'seen' through the front of the lens system.

In optics, the exit pupil is a virtual aperture in an optical system.

The f-number of an optical system (such as a camera lens) is the ratio of the system's focal length to the diameter of the entrance pupil.

Focal length

The focal length of an optical system is a measure of how strongly the system converges or diverges light.

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.
