How is Infra-Red radiation detected at the focus of a telescope?

You need special optics to focus infra-red.
The longer wavelengths do not focus at the same point (they are bent less by refraction).
Mirror optics are better.

A telescope collects electromagnetic radiation from outer space and does what to it?
Yes a telescope collects electromagnetic radiation (light) an then brings this light to a focus so that the source of the light is magnified. The larger the diameter of the telescope, the more light it collects making the image at the focus brighter so as well as magnifying the image a telescope also allows one to see fainter objects.
How is an optical telescope different from the others?
An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.
What is the advantage of having telescope that collect and focus radiation?
All telescopes collect or focus radiation in some way, because visible light is a form of electromagnetic radiation. The advantages of telescopes include being able to see things that are far away, as well as the ability to observe heavenly bodies.
What does a telescope focus and collect from space for closer observation?
it gather electro magnetic radiation from object in space and concern trites it for better observation
For what purpose are most telescope designed?
most telescopes are used to collect and focus on different types of electromagnetic radiation from stars. Including visible light
Does the Hubble Telescope use mirrors or lenses to focus the image?
The Hubble Telescope uses both mirrors and lenses to focus on images.
What type of telescope minimizes color focus problems?
A telescope with achromatic lenses.
What do you call a telescope that uses a lens to focus light?
It is called a refracting telescope.
This telescope uses mirrors to gather and focus light energy?
Newtonian telescope
Telescope that uses several mirriors to combine and focus light?
A reflecting telescope forms an image by using a combination of curved mirrors to focus light. It was invented as an alternative to the refracting telescope.
What is the name of the telescope that uses convex lenses to gather and focus light?
Refracting telescope.
Where is the focus of a refracting telescope?
The focus is between the two lenses, closer to the eyepiece
