摘要
亚利桑那大学望远镜项目中用于干涉测量6.5 m f/1.25主镜光学表面的仪器必须补偿与最佳拟合球的表面偏差超过800 μm。光学测试中的误差对最终图像的贡献不得超过0.04角秒FWHM，并且圆锥常数必须保持在0.01%。本文概述了用于测量这些巨镜的仪器，以达到如此高的精度。
Null correctors for 6.5-m f/1.25 paraboloidal mirrors
The instruments used to interferometrically measure the optical surfaces of the 6.5-m f/1.25 primary mirrors for the University of Arizona telescope projects must compensate over 800 μm surface departure from the best fitting sphere. The errors in the optical test must not contribute more than 0.04 arc seconds FWHM to the final image and the conic constant must be held to 0.01%. This paper presents an overview of the instruments used to measure these giant mirrors to such high accuracy.
