Abstract

The reflective null corrector used to manufacture of the Hubble Space Telescope contains valuable information about the prescription of the primary mirror since an excellent null was achieved between the null-corrector wave front and the primary-mirror wave front. During the Phase I measurements, the leading cause of the spherical aberration, the field lens position error, was discovered and remeasured to an accuracy of +/-0.005 mm. To derive the conic constant of the primary mirror to an accuracy of +/-0.0003, we remeasured the parameters of the reflective null corrector that could contribute to the spherical aberration of the primary mirror.

摘要

用于制造哈勃太空望远镜的反射式零位校正器包含了有关主镜像差校正的宝贵信息，因为在校正器波前和主镜波前之间实现了出色的零位校正。在第一阶段测量期间，发现了球差的主要原因——场镜位置误差，并将其重新测量至±0.005毫米的精度。为了将主镜的二次曲面常数推导至±0.0003的精度，我们重新测量了可能导致主镜球差的反射式零位校正器的参数。
