ABSTRACT Large telescope mirrors are typically measured using interferometry, which can achieve measurement accuracy of a few nanometers.

One of the objectives is to show with practical examples, success stories, what optical metrology can do to measure large mechanical structures for space optics.

The use of the laser tracker is explored to define the metrology for aligning optical systems, including the use of mirrors and windows, and it is shown how to use the tracker for measuring For mounting large optical elements, particularly sophisticated opto-mechanics are often required in addition, so that one achieves precise positioning while avoiding detrimental effects of

Antonio Castelo-Porta Optical metrology is one of the key technologies in today’s manufacturing in-dustry. It can be generally defined as the science of measuring with light, and it is widely Telescopes with very large diameter or with wide fields require convex secondary mirrors that may be many meters in diameter. The optical surfaces for these mirrors can be More recently, “dynamic interferometry” has been implemented for vibration-insensitive measurement of large optics. The data is used to control polishing operations, verify dimensional stability of support structures, align
