Prism usually refers to:
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models.
A spotting scope is a compact lightweight portable telescope optimized for detailed observation of distant objects. They are used as tripod mounted optical enhancement devices for various outdoor activities such as birdwatching, skygazing and other naturalist activities, for hunting and target shooting to verify a marksman's shot placements, for tactical ranging and surveillance, and for any other application that requires higher magnification than ordinary binoculars.
An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides. Not all optical prisms are geometric prisms, and not all geometric prisms would count as an optical prism. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, acrylic and fluorite.
In optics, an Abbe prism, named for its inventor, the German physicist Ernst Abbe, is a type of constant deviation dispersive prism similar to a Pellin–Broca prism.
In optics, a Porro prism, named for its inventor Ignazio Porro, is a type of reflection prism used in optical instruments to alter the orientation of an image.
Ignazio Porro was an Italian inventor of optical instruments.
A Porro–Abbe prism, named for Ignazio Porro and Ernst Abbe, is a type of reflection prism used in some optical instruments to alter the orientation of an image. It is a variant of the more common double Porro prism configuration.
An Abbe–Koenig prism is a type of reflecting prism, used to invert an image. They are commonly used in binoculars and some telescopes for this purpose. The prism is named after Ernst Abbe and Albert Koenig.
A roof prism, also called a Dachkanten prism or Dach prism, is a reflective prism containing a section where two faces meet at a 90° angle, resembling the roof of a building and thus the name. Reflection from the two 90° faces returns an image that is flipped laterally across the axis where the faces meet.
A Schmidt–Pechan prism is a type of optical prism used to rotate an image by 180°. These prisms are commonly used in binoculars as an image erecting system. The Schmidt–Pechan prism makes use of a roof prism section. Binoculars designs using Schmidt–Pechan prisms can be constructed more compactly than ones using Porro or Uppendahl roof and Abbe–Koenig roof prisms.
Brucato is an Italian surname. It is relatively uncommon in modern Italy, having been identified among only 133 citizens and ranking as the 27,322nd most common surname in the nation. It is equally scarce in the United States, appearing 825 times in the 2000 Census and ranking #27,496.
De Bono is a surname of Italian origin, rooted from the Latin word "bonus" meaning "good". It originated in Northern Italy and its first known documentation appears in Parma in the thirteenth century, where it is recorded in deeds of property sale.
In optics, a relay lens is a lens or a group of lenses that receives the image from the objective lens and relays it to the eyepiece. Relay lenses are found in refracting telescopes, endoscopes, and periscopes to optically manipulate the light path, extend the length of the whole optical system, and usually serve the purpose of inverting the image. They may be made of one or more conventional lenses or achromatic doublets, or a long cylindrical gradient-index of refraction lens.
Montanari is an Italian surname meaning mountaineer or highlander. Its highest concentration occurs in the region of Emilia Romagna. Notable people with the surname include:
Fisichella is an Italian surname, originally from Sicily, present in around 130 Italian municipalities.
Pedro Antonio Porro Sauceda is a Spanish professional footballer who plays as a right-back or right wing-back for Premier League club Tottenham Hotspur and the Spain national team. He is known for his passing ability, vision, and tackling ability.
Maione is a surname most prevalent in the Italian regions Campania, Lazio and Calabria. In Calabria a toponymic origin of the name is suggested. Notable people with the surname include:
A Perger prism or Perger–Porro prism system is a prism, that is used to invert an image. The special feature of this prism is that, like a traditional double Porro prism system, it manages this with only four beam deflections and has neither a roof edge with the accompanying phase correction problems, a mirrored surface or an air gap. However, in contrast to the traditional double Porro prism, it leads to a significantly reduced eyepiece/objective axis offset. The reduced beam offset allows for slimmer, more straight binocular housings usually found in roof prism binoculars. Complicating production requirements make high-quality roof prism binoculars relatively costly to produce compared to in optical quality equivalent Porro prism or "Perger–Porro prism system" binoculars.
