It bends the light with lenses and mirrors, so your answer would be yes.
Infrared the answer is a refracting telescope :p
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
That telescope you are refering to is called a refracting telescope.
refracting
It is called a refracting telescope.
Refracting telescope.
It gathers the light coming from an object.
Concave Mirrors
They don't. They are the same.
"Optical", in this case, simply means that they work with light.
Reflecting telescopes don't use lenses - they use mirrors (hence 'reflecting'). Light goes in the top, hits a concave mirror at the bottom of the tube which makes the light converge when it is reflected, then bounces back up to the top where it hits a smaller secondary mirror, where it is directed down the eyepiece. Do you mean refracting telescopes? If so then these do use lenses, the amount depends on the telescope. The most simple form has an objective lens which focuses the light, and then an eyepiece which has a lens in it to magnify the image. The objective lens is convex on the side pointing out of the telescope, and is flat on the other side.
