В состав ГЭТ 186-2017 включены спектральный эллипсометр, оснащённый двухкоординатным столом для измерений на сетке 10×10 точек, и интерференционный профилометр, с помощью которого измеряется двумерная карта отклонений от 90° нормалей к поверхности объекта. В точках сканирования, где отклонение нормали превышает 0,01°, измерения не производятся. Измерение двумерного пространственного распределения эллипсометрических углов позволяет восстанавливать пространственные распределения толщины и комплексного показателя преломления покрытий по площади исследуемого изделия. ГЭТ 186-2017 обеспечивает единство измерений в приоритетных направлениях науки и техники, таких как микроэлектроника, оптика, приборостроение. Основными потребителями ГЭТ 186-2017 являются организации, занимающиеся разработкой новых изделий микроэлектроники, солнечных батарей, оптики, в частности лазерных гироскопов. В состав таких изделий входят нанесённые на подложки упорядоченные многослойные структуры, толщину которых контролируют с помощью различных типов эллипсометров, в том числе эллипсометров изображений.</p></abstract><trans-abstract xml:lang="en"><p>Paper describes the structure, principle of work and metrological characteristics of the State primary standard of ellipsometric angles units GET 186-2017, which provides measurement of the two-dimensional spatial distribution of ellipsometric angles. The GET 186-2017 includes a spectral ellipsometer equipped with a two-coordinate table for measurements on a grid of 10×10 points, and an interference profilometer which measures a two-dimensional map of deviations from 90° normal to the surface of the object. At scan points where the normal deviation exceeds 0.01° there are no measurements. Measurement of the two-dimensional spatial distribution of ellipsometric angles allows restoring the spatial distribution of the thickness and complex refractive index of coatings over the area. GET 186-2017 ensures the uniformity of measurements in priority areas of science and technology, such as microelectronics, optics, instrument making. The main consumers of GET 186-2017 are organizations involved in the development of new products of microelectronics, solar cells, optics, in particular laser gyroscopes. Such products includes ordered multilayer structures deposited on substrates, which are controlled using various types of ellipsometers, including image ellipsometers.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>талон</kwd><kwd>поверочная схема</kwd><kwd>эллипсометрия</kwd><kwd>эллипсометрические углы дельта Δ и пси ψ</kwd><kwd>эллипсометр изображений.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>the standard</kwd><kwd>the verification schedule</kwd><kwd>ellipsometry</kwd><kwd>ellipsometric angles psi ψ and delta Δ</kwd><kwd>imaging ellipsometer.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">.
