Descubre la Tabla de Michel-Levy, una herramienta para identificar los minerales por sus colores de interferencia en el microscopio óptico.
The Michel-Levy chart is utilized by comparing the highest-order interference colors displayed by the specimen in the microscope to those contained on the chart. Once the appropriate color has been located, the nearest vertical line along the interference color is followed to the nearest horizontal line representing the known thickness.
Para ello necesitamos identificar el color de interferencia del mineral. A partir de este color y conociendo el espesor de la lámina delgada (normalmente 30µm), utilizamos la tabla de Michel-Lévy para estimar la birrefringencia.
Auguste Michel-Lévy (1844–1911) French geologist, Inspector General of Mining and director of the Geological Survey in France, made a name for himself by his research into extrusive rocks, their microscopic structure and origin. Until this day, the interference color chart proposed by him in 1888 remains an important tool in the identi-
15 de jun. de 2018 · Michel-Levy Birefringence Chart. Quantitative analysis of the interference colors observed in birefringent samples is usually accomplished by consulting a Michel-Levy chart similar to the one illustrated in the tutorial window below.
Learn how to use the Michel Levy chart to help identify unknown materials and discover important optical information about known materials.
In optical mineralogy, an interference colour chart, also known as the Michel-Levy chart, is a tool first developed by Auguste Michel-Lévy to identify minerals in thin section using a petrographic microscope.
