Live Video Review: Application of Optical Microscopy in Geological Analysis

Optical microscopy in geological analysis has become one of the conventional research techniques, its advantages first lie in the non-destructive nature of optical detection, the analysis of samples to provide safety; The second is the large distance depth of field, which can more clearly observe the micro-area morphology; The third is the 3D modeling and measurement function of micromorphology, which can quantify the physical structure characteristics of microfields

This course helps you select the most suitable equipment for analysis and research

Introduction to the general configuration of DM4P

Imaging effect of some rock samples

Microscopic imaging effect of mica-related samples

Polarized light microscopes also have many configurations to choose from, such as: microscope hot stage, cathodoluminescence meter, spectrophotometer and other diverse application configuration needs to meet the needs of different types of researchers

Leica Optical Observation and Composition Analysis in One: The DM6M LIBS system also meets the requirements for the detection of such samples, from visual analysis to elemental detection, with rapid elemental identification in just a few seconds and no additional sample preparation required
