    The Nicholas U. Mayall Telescope, also known as the Mayall 4-meter Telescope, is a four-meter (158 inches) reflector telescope located at the Kitt Peak National Observatory in Arizona and named after Nicholas U. Mayall. It saw first light on February 27, 1973, and was the second-largest telescope in the world at that time. [2]

    These lenses, and the telescope's filters, are built into the camera assembly. The first lens, at 1.55 m in diameter, is the largest lens ever built, [39] and the third lens forms the vacuum window in front of the focal plane. [38] Unlike many telescopes, [40] the Rubin Observatory makes no attempt to compensate for dispersion in the atmosphere ...

    en.wikipedia.org/wiki/Dark_Energy_Survey

    The Dark Energy Survey (DES) is an astronomical survey designed to constrain the properties of dark energy.It uses images taken in the near-ultraviolet, visible, and near-infrared to measure the expansion of the universe using Type Ia supernovae, baryon acoustic oscillations, the number of galaxy clusters, and weak gravitational lensing.
