The main optical element of a refracting telescope is the objective lens. This lens collects and focuses light from distant objects, forming an image that can be magnified and observed through an eyepiece.
An optical telescope collects and focuses visible light from celestial objects like stars, planets, and galaxies. This light is then directed to a detector or eyepiece for observation and analysis.
A reflector telescope collects light with a mirror. The mirror is located at the back of the telescope and reflects the incoming light to a focal point where it is then collected by an eyepiece for viewing.
"Optical", in this case, simply means that they work with light.
The observatory had not yet opened, so we waited outside until it did.
Example of an optical instrument? (not sample) Microscope.
An optical telescope is the simplest instrument to view the heavens.
That instrument is called a radio telescope. It collects and concentrates radio waves emitted by celestial objects in space, allowing scientists to study the universe beyond what is visible to the human eye.
Optical or radio telescope
A telescope is an optical instrument used to make distance views and objects appear closer to the user.
Neither the violin nor the Eb Sousaphone does.

an optical telescope
The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.
