List of largest optical reflecting telescopes. This list of the largest optical reflecting telescopes with objective diameters of 3.
The mirrors themselves can be larger than the aperture, and telescopes may use aperture synthesis achieved by interferometry. Telescopes designed to be used as optical astronomical interferometers such as the Keck I and II used together as the Keck Interferometer (up to 8. When the two mirrors are on one mount, the combined mirror spacing of the Large Binocular Telescope (2.
Largest does not always equate to being the best telescopes, and overall light gathering power of the optical system can be a poor measure of a telescope's performance. Space- based telescopes, such as the Hubble Space Telescope, take advantage of being above the Earth's atmosphere to reach higher resolution and greater light gathering through longer exposure time. Location in the northern or southern hemisphere of the Earth can also limit what part of the sky can be observed. Table of reflecting telescopes.

Multiple mirror telescopes that are on the same mount, may have a working beam combiner, and can form an image may be ranked by an equivalent aperture to this reported by sources. HET- style or fixed telescopes are ranked by an equivalent aperture also.

The Steward Observatory Mirror Lab produced the 6. Large Optical Test and Integration Site of Lockheed Martin, used for vacuum optical testing of other telescopes. Segmented mirrors are also referred to as mosaic mirrors. Single mirrors are also referred to monolithic mirrors, and can be sub- categorized in types, such as solid or honeycomb. Countries which contain several of these telescopes are color- coded for identification. Top telescopes of 2.
However, these astronomical interferometers are less flexible in use, and many interferometers cannot form images or see faint objects despite their high peak angular resolution. The largest telescope during the first decade of the 2.

Note other wavelengths of telescopes can be much larger physically, such as the 3. Arecibo radio telescope, but since radio wavelengths are also larger, this does not necessarily translate into brighter or higher resolution images.
