Abstract

The figuring of the 3.5 m primary mirror of the large telescope is described. The execution of final tests was carried out in a vertical test tunnel by means of a laser interferometer, using a compensating system. A special sequence of interferograms was applied aiming to suppress the thermal, accidental, and environmental influences. The wave front errors were evaluated accordingly. The results show that the standard deviation due to the mirror is 24 nm, out of total standard deviation of 49 nm taken as an avarage of 24 interferograms.© (1982) COPYRIGHT SPIE--The International Society for Optical Engineering.
