Telescope device used to form magnified images of distant objects. To make this possible an optical telescope uses the following two instruments.

Telescopes Astronomy

Refractor telescopes that use lenses reflector telescopes that use mirrors and catadioptric telescopes that use mirrors with a lens design.

Uses of optical telescope. Refractors which use lenses. This visual can be in the form of a photo or moving images. Refractors use lenses to refract bend incoming light through a tube to a focal point.

An optical telescope is an instrument that can make distant objects appear much closer. It provides a means of collecting and analyzing radiation from celestial objects even those in the far reaches of the universe. Reflectors which use mirrors.

According to plotner optical telescopes come in three varieties. Optical telescopes gather and focus on visible light to form a magnified image of an object and allow a direct view. Optical telescope has three variants.

The first known practical telescopes were refracting telescopes invented in the netherlands at the beginning of the 17th century by using glass lenses. Most telescopes and all large telescopes work by using curved mirrors to gather and focus light from the night sky. Electronic image sensors can also be used to collect and analyze the data.

Objective lens or primary. A telescope is a tool that astronomers use to see faraway objects. Refracting telescopes are the long tube shaped telescopes which you might imagine galileo using.

Refractors typically have two lenses. Optical telescopes help photographers stargazers and astronomers spot the details of an object too distant to see in detail with the naked eye. The telescope is undoubtedly the most important investigative tool in astronomy.

There are refracting telescopes refractors and reflecting telescopes reflectors. There are three primary types of optical telescope. The first telescopes focused light by using pieces of curved clear glass called lenses.

A telescope is an optical instrument using lenses curved mirrors or a combination of both to observe distant objects or various devices used to observe distant objects by their emission absorption or reflection of electromagnetic radiation. 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.
