May 12 2020 A refracting telescope or a refractor uses a combination of lenses to produce images of distant objects eg stars and planets that would otherwise not be visible with the human eye A simple refracting telescope is made up of two lenses which are called the objective and the eyepiece The principle of a simple refracting telescope is that

Nov 08 2000 How They Work This is the simplest telescope design you could have A big lens gathers the light and directs it to a focal point and a small lens brings the image to your eye A telescope is an amazing device that has the ability to make faraway objects appear much closer Telescopes come in all shapes and sizes from a little

Sep 03 2021 A telescope is a tool that astronomers use to see faraway objects Most telescopes and all large telescopes work by using curved mirrors to gather and focus light from the night sky The first telescopes focused light by using pieces of curved clear glass called lenses

The principle of operation of the Keplerian telescope fig 2 is relatively simple The objective forms a real image diminished in size and upsidedown of the object observed The eyepiece which consisting of a converging lens with short focal length is actually a magnifying lens enlarges the image formed by the objective

Diagram of a simple telescope Parallel light rays enter from the left pass through the objective lens come to a focus at the focal plane and exit through the eyepiece lens The focal length of the objective is F and the focal length of the eyepiece is f

Folding Mirrors The Webb Telescope team also decided to build the mirror in segments on a structure which folds up like the leaves of a dropleaf table so that it can fit into a rocketThe mirror would then unfold after launch Each of the 18 hexagonalshaped mirror segments is 132 meters 43 feet in diameter flat to flat

Jan 24 1986 The first large Schmidt telescope was a 12m instrument covering a field about 6 across and put into operation on Palomar Mountain in the early 1950s Several telescopes of this type and size have since been built in both hemispheres The principle of the Schmidt telescope has also been adapted to cameras used in many spectrometers

Draw a schematic ray diagram of a reflecting telescope

A reflecting telescope is as shown below In a reflecting telescope an image is formed by reflection from a curved mirror The image formed is then magnified by a secondary mirror Advantages of reflecting telescope over a refracting telescope are1 There is no chromatic aberration for reflecting telescopes as the objective is a mirror 2 Spherical aberration is reduced in the case of

Basic Telescope Optics A simple working telescope requires nothing more than a pair of lenses mounted in a tube The lens in front known as the objective lens focuses an image the lens in back known as the eyepiece lens magnifies that image Although it may seem like a crude device a simple telescope nicely illustrates the basic working principles of more powerful astronomical instruments

On this page diagrams schematically represent the telescope objective as a single refracting lens but it may without changing the optical characteristics be a dioptric system comprising one or more lenses a catoptric system one or more mirrors or a catadioptric system a combination of mirrors and lenses
