Difference between Lens (optics) and Refracting telescope

Lens (optics) vs. Refracting telescope

A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope).

Similarities between Lens (optics) and Refracting telescope

Lens (optics) and Refracting telescope have 24 things in common (in Unionpedia): Achromatic lens, Binoculars, Cardinal point (optics), Catadioptric system, Chester Moore Hall, Dispersion (optics), Eyepiece, F-number, Fluorite, Focal length, Focus (optics), Glass, Glasses, John Dollond, Lens (optics), Long-focus lens, Magnification, Moon, Netherlands, Optical telescope, Polishing, Refraction, Virtual image, Visible spectrum.

Achromatic lens

An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration.

Binoculars

Binoculars or field glasses are two telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects.

Cardinal point (optics)

In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system.

Catadioptric system

A catadioptric optical system is one where refraction and reflection are combined in an optical system, usually via lenses (dioptrics) and curved mirrors (catoptrics).

Chester Moore Hall

Chester Moore Hall (9 December 1703, Leigh, Essex, England – 17 March 1771, Sutton, Surrey) was a British lawyer and inventor who produced the first achromatic lenses in 1729 or 1733 (accounts differ).

Dispersion (optics)

In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency.

Eyepiece

An eyepiece, or ocular lens, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes.

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.

Fluorite

Not to be confused with Fluoride. Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2.

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.

Glass

Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics.

Glasses

Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears.

John Dollond

John Dollond FRS (10 June O.S. (21 June N.S.) 170630 November 1761) was an English optician, known for his successful optics business and his patenting and commercialization of achromatic doublets.

Long-focus lens

In photography, a long-focus lens is a camera lens which has a focal length that is longer than the diagonal measure of the film or sensor that receives its image.

Optical telescope

An optical telescope is a telescope that gathers and focuses light, mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct view, or to make a photograph, or to collect data through electronic image sensors.

Polishing

Polishing is the process of creating a smooth and shiny surface by rubbing it or using a chemical action, leaving a surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations.) In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values.

Refraction

Refraction is the change in direction of wave propagation due to a change in its transmission medium.

Virtual image

In optics, a virtual image is an image formed when the outgoing rays from a point on an object always diverge.
