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]

Aperture

In optics, an aperture is a hole or an opening through which light travels.

Camera

A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both.

New!!: Telecentric lens and Camera · See more »

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

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.

Crosstalk

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.

Euro

The euro (sign: €; code: EUR) is the official currency of the European Union.

Exit pupil

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

New!!: Telecentric lens and Exit pupil · See more »

F-number

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.

Four Thirds system

The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) and mirrorless camera design and development.

Image sensor

An image sensor or imaging sensor is a sensor that detects and conveys the information that constitutes an image.

Irradiance

In radiometry, irradiance is the radiant flux (power) received by a surface per unit area.

Lens (optics)

A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.

Light-emitting diode

A light-emitting diode (LED) is a two-lead semiconductor light source.

Machine vision

Machine vision (MV) is the technology and methods used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance, usually in industry.

Magnification

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

Metrology

Metrology is the science of measurement.

Optical resolution

Optical resolution describes the ability of an imaging system to resolve detail in the object that is being imaged.

Orthographic projection

Orthographic projection (sometimes orthogonal projection), is a means of representing three-dimensional objects in two dimensions.

Photographic film

Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals.

Photolithography

Photolithography, also termed optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate.

Radiometry

Radiometry is a set of techniques for measuring electromagnetic radiation, including visible light.

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.

Semiconductor

A semiconductor material has an electrical conductivity value falling between that of a conductor – such as copper, gold etc.

Three-CCD camera

A three-CCD (3CCD) camera is a camera whose imaging system uses three separate charge-coupled devices (CCDs), each one receiving filtered red, green, or blue color ranges.

United States dollar

The United States dollar (sign: $; code: USD; also abbreviated US$ and referred to as the dollar, U.S. dollar, or American dollar) is the official currency of the United States and its insular territories per the United States Constitution since 1792.
