A method for measuring a semifinished prism in which a first test beam path is produced, by which a first test image is imaged to infinity, and in which the first test beam path is guided as an incident beam path onto a first non-polished surface of the prism. A beam path reflected from the first non-polished surface is captured by a telescope, wherein the first test image is imaged onto a detector in the telescope. The incident beam path forms an obtuse angle with the reflected beam path. A second test beam path reflected from a second surface of the prism is captured by a telescope, wherein a second test image, which is imaged to infinity by the second test beam path, is imaged onto a detector by the telescope. The angle between the first surface and the second surface is determined on the basis of the difference between an orientation of the first surface, derived from the first test image, and an orientation of the second surface, derived from the second test image. The invention also relates to an associated measuring device.

Systems and methods for testing and characterization of optical surfaces which works equally well on concave, flat, convex, and non-conic optical surfaces, and which does not require that a master surface be first produced. The method is automatic and requires little human intervention. It provides an extremely high degree of accuracy, and provides repeatability of measurements within a minuscule tolerance of error. The method determines the evolute of the surface automatically, deterministically, and repeatably via orthogonal reflection by ascertaining the evolute of the surface's figure along multiple diameters of the surface.

A method for performing an X-ray diffraction analysis of a crystal sample using a multi-dimensional detector that integrates an X-ray diffraction signal while the position of the sample relative to an X-ray source is changed along a scan direction. The resulting image is compressed along the scan direction, but may be collected very quickly. The capture of both on-axis and off-axis reflections in a single image provides a common spatial frame of reference for comparing the reflections. This may be used in the construction of a reciprocal space map, and is useful for analyzing a sample with multiple crystal layers, such as a crystal substrate with a crystalline film deposited thereupon.
