About the Microscope Slide Scanner
![The Microscope Slide Scanner and the Zeiss ZEN software is easy to use in analyses of geological material prepared as a thin section.

The slide scanner contains an optical microscope with a powerful light source and camera. Slides are automatically loaded onto the microscope stage and moved to different positions, so that many separate micrographs can be taken, which are simultaneously stitched together to produce scans of the whole slide within minutes.
Scans can be acquired in cross-polarised light with different angles of polarization to get a full overview of interference colour, undulose extinction, and other microstructural features.
Three-dimensional objects can be imaged sharply by combining pictures taken at different focal depths (Z-stacking).
Users can view, process, and analyse the scans on their own time using the free version of the Zen software available on the Zeiss website.
Both the Microscope Slide Scanner and the petrographic microscopes are in BookitLab!
The laboratory can by appointment be used for research activities and/or to assist students at the Department of Geosciences.
