All telescopes collect and focus light. Some concentrate on visible light while others look for infra-red, radio and microwave radiation.
most telescopes are used to collect and focus on different types of electromagnetic radiation from stars. Including visible light
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
Both types of telescope collect and focus electromagnetic radiation for observational purposes, the difference is their band of observed frequencies. Radio telescopes are used for the radio frequencies ( ~3km - ~30cm) while optical telescopes are used for frequencies closer to visible light ( ~0.7μm - ~0.4μm). Optical telescopes may also be able to detect infrared and ultraviolet light.
Fluorescent means something is glowing, usually with visible light. Fluorescent means giving off visible (or invisible) radiation as a result of absorbing shorter wavelength 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.
Telescopes are made to view distant objects that cannot be seen clearly with the human eye. Many telescopes only collect light that is visible to the human eye, but others can collect different frequencies of electromagnetic radiation including x-rays, ultraviolet, and infrared.

Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
An "optical" telescope would naturally collect light from optical wavelengths, meaning visible light from ~400-800nm.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.

They study visible light by using optical telescopes.
