Secondary mirror telescope
WebThe modern telescope is equipped with “adaptive optics”: a flexible secondary mirror which creates extremely sharp astronomical images by correcting for distortions created by Earth’s atmosphere. Scientists and engineers at the CfA developed a suite of instruments both to create images and to analyze the spectrum of light from astronomical sources. WebThe TMT telescope optical design is a folded Ritchey-Chrétien. Both the primary and secondary mirrors are hyperboloids, and together form a well-corrected image. The tertiary mirror folds and steers the science beam to any of eight instruments, mounted on the two Nasmyth platforms. The image is formed 20 meters from the center of the tertiary ...
