Definitions for optical telescope
This page provides all possible meanings and translations of the word optical telescope
an astronomical telescope designed to collect and record light from cosmic sources
An optical telescope is a telescope which is used to gather and focus light mainly from the visible part of the electromagnetic spectrum to directly view a magnified image for making a photograph, or collecting data through electronic image sensors. There are three primary types of optical telescope: refractors which use lenses, reflectors which use mirrors, and catadioptric telescopes which use both lenses and mirrors in combination. A telescope's light gathering power and ability to resolve small detail is directly related to the diameter of its objective. The larger the objective, the more light the telescope can collect and the finer detail it can resolve. Telescopes and binoculars can be used for activities such as observational astronomy, ornithology, pilotage and reconnaissance, or watching sports or performance arts.
