Optical Microscopy

The institute provides various possibilities to perform optical light microscopy analyses on polished samples. These methods include:

• Polarisation microscopes for transmitted light (diascopic, thin sections of rocks) Objectives: 2, 5, 10, 20, 40, 60, 100x.
 Use of 
universal stage and pointcounter

• Polarisation microscopes for reflected light (episcopic, opaque minerals)
• Microscope for fluid inclusion microanalysis

• Nomarski-DIC, 
differential interference contrast method (epi- and diascopic)

• Stereomicroscopes (“binoculars”) 5-100x, inclined and transmitted light, dark field

• Photomicrography is possible with all types of microscopes at the Institute of Geochemistry and Petrology
  
• Macro-photography including easy-to-do photos of a whole thin section or grain mount; with transmitted and incident light (Aristophot stand)
