Abstract
Изобретение относитс к оптическому приборостроению и может быть использовано дл измерени показател преломлени твердых и жидких веществ. Цель изобретени - повышение точности измерений. Рефрактометр состоит из источника 1 когерентного излучени , светоделителей 2 и 7, полупрозрачной пластины 5, зеркал 4 и 6, счетчиков 8 - 10 интерференционных полос. Кювета 3 дл исследуемого вещества выполнена в виде клина, установлена с возможностью перемещени вдоль грани ВС. При смещении клина вдоль этой грани фиксируют количество интерференционных полос на счетчиках и вычисл ют по формуле показатель преломлени , при этом случайные смещени кюветы не вли ют на результат измерений. 2 ил.The invention relates to optical instrumentation and can be used to measure the refractive index of solid and liquid substances. The purpose of the invention is to improve the measurement accuracy. The refractometer consists of a source of coherent radiation 1, beam splitters 2 and 7, a translucent plate 5, mirrors 4 and 6, and counters of 8 to 10 interference fringes. The cuvette 3 for the test substance is made in the form of a wedge, mounted to move along the face of the sun. When the wedge is displaced along this facet, the number of interference fringes is recorded on the counters and the refractive index is calculated using the formula, while the random displacements of the cell do not affect the measurement result. 2 Il.
