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.
Descubre la Tabla de Michel-Levy, una herramienta para identificar los minerales por sus colores de interferencia en el microscopio óptico.
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-
This Michel-Lévy color chart from Rosenbusch and Wülfing’s Fifth Edition is the version that is said to have been framed and was on the wall of Chamot’s laboratory at Cornell University. Over the last 75 years or so, the Michel-Lévy interference color chart appears in virtually all optical crystallography textbooks, or the chart has been ...
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
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).
1 de sept. de 2012 · Results demonstrate that a Michel-Lévy chart can easily be calculated using programming and published colour transformation functions. Because of the wide gamut range of the interference colours, a colour clipping of the red values is necessary.
