Description of equipment

The Opton Zeiss microscope is designed for optical microscopy in transmitted and reflected light in air. It allows micropetrographic examination of rock in rubble in normal transmitted light, as well as of ore and coal (or organic matter) in normal reflected light. Using a UV filter and an Hg lamp, it allows the fluorescence of organic matter and fluorescent minerals to be investigated. Equipped with a light stabiliser, a camera and a command unit for focusing the image and for adjusting the photographic settings. The eyepieces (10 × magnification) are permanently mounted. The lenses can be interchanged at magnifications of 5 ×, 10 ×, 20 ×, 25 ×, 50 ×. The maximum magnification that can be achieved with very well polished surfaces is therefore 500 ×, but in practice magnifications of 100 ×, 200 × and 250 × are most commonly used.

Numerous investigations have been carried out with the Opton Zeiss microscope on samples of our coals, mainly in Zasavje, Velenje and Kanižarice, and on sedimentary clastic rocks.
