List of largest infrared telescopes, by diameter of entrance aperture, oriented towards large observatories dedicated to infrared astronomy. Infrared has a number of challenges, especially for ground-based observatories but also in space. The near-infrared is similar to optical telescopes, although the longer wavelength infrared can also be related to aspects of radio and microwave astronomy. A major implication of looking at longer wavelengths are that infrared telescopes have a lower diffraction limit all else being compared to a visible light telescope, because the wavelength of light they are looking is longer. Secondly, infrared is heat, so the telescopes can be much more sensitive to emission of heat.
Overall
Infrared observations from Earth's surface are possible in a limited way but can be very dependent on location and atmospheric conditions. Water vapor blocks much of the infrared band in Earth's atmosphere, although some limited observations are possible and there is a number of infrared focused observatories, which often also view optical visible wavelengths. Sometimes other optical telescopes can make infrared observations if they are equipped with the right detectors, even if they are not dedicated infrared observatories. For ground-based observatories, the location can make a big difference in how much observation is possible.
