为了对哈勃空间望远镜主镜的球差进行校正，研制了5个非球面非球面镜片，它们分别代表了3台科学仪器的校正值。在供应商对这些反射镜进行验收测试期间，开发了一种快速而简单的方法来验证非球面面形。这项技术已经用于与三个仪器处方相关的三个非球面上。结果表明，三种非球面的测量精度均达到了本试验所要求的极限精度。
To correct for the spherical aberration in the Hubble Space Telescope primary mirror, five anamorphic aspheric mirrors representing correction for three scientific instruments have been fabricated as part of the development of the corrective-optics space telescope axial-replacement instrument (COSTAR). During the acceptance tests of these mirrors at the vendor, a quick and simple method for verifying the asphere surface figure was developed. The technique has been used on three of the aspheres relating to the three instrument prescriptions. Results indicate that the three aspheres are correct to the limited accuracy expected of this test.
