Laboratory of optical microscopy and cathodoluminescence is located in the building of the Institute of Geological Sciences and includes rooms 311 and 312. In the Laboratory there are five polarising microscopes available and  a special one for the cathodoluminescence. One can book worktime making notice in a special book. Please contact prof. Zbigniew Sawłowicz or Beata Stożek M.Sc. before the first use of cathodoluminescence.   

 

Cathodoluminescency

Cathodoluminescency (Cl) is the emission of photons of characteristic wavelengths in the visible spectrum  from a material that is excited by high-energy electron bombardment.

Features:

  • Identification of minerals, their characteristics and relationships (eg.: colour, zoning, micro-fracturing)
  • To determine the progress of diagenetic processes and succession of hydrothermal minerals.

Devices:

A cold cathode cathodoluminescence microscope CLmk3A of Cambridge Image Technology Ltd. coupled to the Nikon Eclipse 50T, with the ability to record images with a digital camera Canon EOS 400 or Nikon 5300, respectively, controlled by programs Canon - EOS or Nikon Utility - Cool View.

 

Transmitted light polarized microscopy

The study of minerals and rocks using optical microscopy in polarized light gives a possibility to determine many features and parameters of rock such as the structure and texture,and mineral identification of the rock components. The addition of a planimeter allows quantitative analysis of the rock. These studies can be the basis for picking samples for further study, eg. XRD, FTIR, SEM and CL.

Devices:

Transmitted and reflected light polarizing microscope NIKON Eclipse E600-POL with the ability to record images with digital cameras Canon EOS 400 or Nikon 5300, respectively, controlled by programs Canon - EOS or Nikon Utility - Cool View.

Transmitted light polarizing microscope NIKON Eclipse E200-POL with the ability to record images with the digital camera NIKON Coolpix 950, controlled by program Nikon Utility - Cool View.

Transmitted and reflected light polarizing microscope Carl Zeiss Jena Laboval with the ability to  record images using the camera  Practica BCA M.

Transmitted light polarizing microscope Carl Zeiss Jena POL coupled to the microscope  integration table ELTINOR 4 (nine channels, ROW Rathenow, DDR). The table is used for the planimetric microscopical analysis.

 

Reflected light polarized microscopy

Reflected light polarized microscopy enables identification of ore minerals and observations of relationship with gangue minerals. These studies can be the basis for picking samples for further study, eg. XRD and SEM.

Devices:

Transmitted and reflected light polarizing microscope NIKON Eclipse E600-POL with possibility of recording the images using a digital camera Canon EOS 400, controlled by a program Nikon - EOS Utility.

Transmitted and reflected light polarizing microscope  Carl Zeiss Jena Laboval with possibility of recording the images using a camera  Practica BCA M.

Reflected light polarizing microscope Carl Zeiss Jena Nephot 21 with possibility of recording the images using a camera.
