| 摘要 |
An aspheric optical test plate assembly is disclosed which permits a qualitative comparison to be made between the surface contour of a known area of an aspheric optical element and the surface contour of an area on the aspheric optical element which should be equivalent to the contour of the known area. The aspheric optical test plate assembly includes an optical test plate in the shape of a segment of a spherical element and means for stressing the element to make its contour approximate the contour of an aspheric surface.
