Pentaprism

Index Pentaprism

A pentaprism is a five-sided reflecting prism used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism. [1]

Anti-reflective coating

An antireflective or anti-reflection (AR) coating is a type of optical coating applied to the surface of lenses and other optical elements to reduce reflection.

Carl Zeiss AG

Carl Zeiss, branded as ZEISS, is a German manufacturer of optical systems, industrial measurements and medical devices, founded in Jena, Germany in 1846 by optician Carl Zeiss.

Chirality (electromagnetism)

The direction of current flow and induced magnetic flux follow a "handness" relationship The term chiral describes an object, especially a molecule, which has or produces a non-superposable mirror image of itself.

Construction

Construction is the process of constructing a building or infrastructure.

Contax

Contax began as a camera model in the Zeiss Ikon line in 1932, and later became a brand name.

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.

Focusing screen

A focusing screen is a flat translucent material, either a ground glass or fresnel lens, found in a system camera that allows the user of the camera to preview the framed image in a viewfinder.

Light

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum.

Medium format (film)

Medium format has traditionally referred to a film format in still photography and the related cameras and equipment that use film.

Mirror

A mirror is an object that reflects light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original light, called specular reflection.

Nikon F

The Nikon F camera, introduced in April 1959, was Nikon's first SLR camera.

Pentamirror

A pentamirror is an optical device used in the viewfinder systems of various single-lens reflex cameras instead of the pentaprism.

Plumb bob

A plumb bob, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical reference line, or plumb-line.

Praktica

Praktica is a brand of camera manufactured by Pentacon in Dresden in eastern Germany, formerly within the GDR prior to German reunification in 1990.

Prism

In optics, a prism is a transparent optical element with flat, polished surfaces that refract light.

Reflex camera

A reflex camera is a camera that permits the photographer to view the image that will be seen through the lens, and therefore to see exactly what will be captured, contrary to viewfinder cameras where the image could be significantly different from what will be captured.

Retroreflector

A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering.

Right angle

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn.

Roof prism

A roof prism (also called a Dach prism or Dachkanten prism, from the German: "Dachkante", lit. roof edge) is a reflective optical prism containing a section where two faces meet at a 90° angle.

Single-lens reflex camera

A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured.

Surveying

Surveying or land surveying is the technique, profession, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them.

System camera

A system camera is a camera with interchangeable components that constitutes the core of a system.

Total internal reflection

Total internal reflection is the phenomenon which occurs when a propagated wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface.
