Product Overview

Description



Details Images


● A telescope is an optical instrument that uses lenses or mirrors and other optics to observe distant objects. Refraction of light through a lens or reflection of light by a concave mirror makes it enter a small hole and converge into an image, which is then seen through a magnifying eyepiece.

● The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. The word telescope now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors.
