First, the customer profile
The Institute of Geology of the Chinese Academy of Geological Sciences is a subsidiary of the China Geological Survey, a national social welfare research institution, and an important part of the national science and technology innovation system. Mainly engaged in basic, public welfare, strategic and cutting-edge geological survey research work, providing basic geological theory and technical support for national geological survey work. At the same time, he undertakes the education and training of research talents in geology, geophysics and geochemistry. In 2016, he was selected as a national demonstration base for innovative talent training. In the past 60 years since its establishment, the Institute of Geology has been basically built into a comprehensive geoscience research institution with complete disciplines, reasonable personnel structure and relatively complete equipment. In regional geological and geological mapping, geotectonics, evolution of life origin and strata, Metamorphic rocks and Precambrian geology, petrology, mineralogy, geochemistry and earth matter science, continental dynamics and mantle dynamics, metallogenic geological background and regional metallogenesis, lithospheric structure and geodynamics, isotope geology In terms of learning, it has formed an advantageous research field and direction that has certain influence at home and abroad.

Two kinds of illuminators do their best
You can configure the Leica DM4 P polarizing microscope to use transmitted or incident light for LED illumination, or you can configure both sources with a single configuration.
• Incident light must be used for reflectance measurements, such as observation of ore or coal.
• Transmitted light is required for birefringence measurements, such as geological sheets, polymer films, or pharmaceuticals.
· In special applications such as geological research, both types of light are essential.
When the microscope is configured to use both incident and transmitted light, the associated objective (with or without the coverslip correction function) should be used with >10x magnification.
The LED illumination of the Leica DM4 P polarized microscope can be selected to use transmitted or incident light.
