Refractor and Reflector.
Optical system: Refractor.
The Equatorial, a refractor with aperture of 26 cm and focal length.
There are two types of telescopes: reflector and refractor.
For a number of years Cooper's big refractor was the largest in the world.
Observations were obtained using an 80mm refractor.
What is the difference between a Refractor Telescope and a Reflector Telescope?
There are two basic kinds of telescopes: a reflector and a refractor.
Usually refractor telescopes have azimuthal mount, making it well suited, for example, for children.
There are two common types of telescopes: refractor and reflector.
The 76-cm(30-inch) refractor telescope that became operational in 1888 was at that time the world's largest telescope.
Here is observed an obvious difference with refractor systems.
Refractor telescopes are useful for monitoring the open space and is not suitable for observation from the balcony or window.
What's the difference between reflector and refractor telescopes?
Its very convenient to observe an open terrain with refractor, but the observations from the open window or balcony is extremely inefficient.
Produce a mirror is easier thanthe lens, reflector telescopes, so with the same lens diameter is much cheaper that the refractor.
If the objective is a convex lens,the telescope is called a refractor, because the lens bends, or refracts, light to form an image.
Make a mirror is easier thanthe lens, so the same reflector telescopes diameter of the lens will be much cheaper that the refractor.
Now part of a Schmidt Museum Photographic refractor(Zonenastrograph), an instrument funded by the Deutsche Forschungsgemeinschaft(DFG) in 1973.
During the period of his management, the observatory expanded considerably and acquired new tools,most remarkably a 30-inch refractor- the largest in the world at that time- installed in 1886.
The Refractor Engine, is a game engine designed by Stockholm-based studio Refraction Games, first developed for the computer game Codename Eagle, which was released in November 1999.
This ring-shaped entrance aperture significantly reduces a portion of the modulation transfer function(MTF) over a range of low spatial frequencies,compared to a full-aperture design such as a refractor.[5] This MTF notch has the effect of lowering image contrast when imaging broad features.
His first was the 40-inch refractor at Yerkes(in Wisconsin) on the left, but then he began building the more revolutionary- and more compact- reflector telescopes, using a large mirror instead of a lens.
For today refractor are the most widespread optical systems of telescopes in the category of amateur devices(they have objective and lens) and reflectors(fitted with objective and a mirror), the next are the systems of Maksutov-Cassegrain and Cassegrain, along with systems of Schmidt-Cassegrain(combined set of mirrors and lenses).
