Descubre la Tabla de Michel-Levy, una herramienta para identificar los minerales por sus colores de interferencia en el microscopio óptico.
These will cause color changes in the specimen, which can be interpreted with the help of a polarization color chart (Michel-Levy chart; see Figure 4). These charts illustrate the polarization colors provided by optical path differences from 0 to 1800-3100 nanometers together with birefringence and thickness values.
Auguste Michel-Lévy (7 August 1844 – 27 September 1911) was a French geologist. He was born in Paris. ... Levy also collaborated with Alfred Lacroix in "Les Minéraux des roches" ... Michel-Lévy Color Chart. This page was last edited on 12 October 2023, at 20:52 (UTC). Text is ...
Many of the Michel-Levy charts printed in textbooks plot higher-order colors up to the fifth or sixth order. The most sensitive area of the chart is first-order red (550 nanometers), because even a slight change in retardation causes the color to shift dramatically either up in wavelength to cyan or down to yellow.
15 de jun. de 2018 · A relationship between interference color and retardation can be graphically illustrated in the classical Michel-Levy interference color chart, which plots retardation on the abscissa and specimen thickness on the ordinate. Birefringence is determined by a family of lines that emanate radially from the origin, each with a different measured value of birefringence corresponding to thickness and ...
4 de nov. de 2012 · Two revisions of the original Michel-Lévy interference colour chart are presented, which give a more precise match to the actual observations in the modern optical microscope and make it easier to determine interference colour and order, and hence also to determine the birefringence of the common silicate minerals. Two revisions of the original Michel-Lévy interference colour chart are ...
