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.
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-
Descubre la Tabla de Michel-Levy, una herramienta para identificar los minerales por sus colores de interferencia en el microscopio óptico.
COLORES DE INTERFERENCIA Y TABLA DE MICHEL-LÉVY. Para cada una de las componentes de la luz blanca, podemos representar las posiciones de los máximos y mínimos de transmisión, frente al retardo, que dependerán de las respectivas longitudes de onda (ver figura).
15 de jun. de 2018 · Interactive Java Tutorials. 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.
The MICHEL-LÉVY interference color chart is a color key to unlock many myster-ies associated with particle analysis. The chart (Hooke College students receive a laminated version) is a valuable aid to the light microscopist in that it graphi-cally relates the thickness, retardation (optical path difference), and birefringence
Michel-Lévy interference colour chart issued by Zeiss Microscopy. 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.
