OPTICAL TELESCOPE Meaning and
Definition
-
An optical telescope is a scientific instrument equipped with lenses or mirrors that utilizes visible light to observe and study celestial objects such as stars, planets, galaxies, and other astronomical bodies. It is a tool designed to capture and magnify the incoming light from these objects, allowing astronomers to gather data about their properties, motion, composition, and behavior.
Comprising an objective lens or a curved mirror, an optical telescope gathers light and directs it towards a focal point. The objective lens or mirror is generally the larger component of the telescope, responsible for collecting the light. On the other hand, a smaller lens or mirror, known as the eyepiece, is located near the focal point and is used to magnify the image produced by the objective.
Optical telescopes can be classified into various types based on their designs, such as refracting or reflecting telescopes. Refracting telescopes use lenses to focus the light, while reflecting telescopes employ mirrors. The light collected by the objective is magnified and focused by the eyepiece, facilitating examination by astronomers or observers.
These telescopes offer a wide range of magnification levels, allowing for detailed observations of celestial phenomena. They have played a crucial role in advancing our understanding of the cosmos, providing groundbreaking discoveries throughout history. With advancements in technology, optical telescopes have progressed significantly, leading to enhanced capabilities and the ability to observe celestial objects with more clarity and precision.

The word "telescope" comes from the Greek word "teleskopos", which means "far-seeing" or "far-observer". The term "optical telescope" is essentially a combination of these words, indicating a device used for observing or seeing distant objects through the use of optics and lenses.
