Digitize your thin sections with Axioscan 7 – the reliable, reproducible way to create high quality, digitized petrography data in transmitted and reflected light. Uniquely designed for petrographic analysis, the Axioscan 7 combines unique motorized polarization acquisition modes with unprecedented speed and a rich software ecosystem for visualization, analysis, and collaboration.
Fully automated acquisition, coupled with ZEISS quality, ensures consistently high image quality, even when processing thousands of samples. Motorized plane and cross polarization allow for both pleochroism and birefringence to be analyzed, whilst circular polarization allows for the rapid assessment of characteristic maximum birefringence regardless of grain orientation.

Go beyond the standard petrographic microscope with the new ZEN Pol Viewer display to navigate the rich petrographic thin sections datasets. It will even automatically synchronize image rotation such that the sample appears exactly as it would in a traditional petrographic light microscope, facilitating the learning process in a teaching environment in the lab and online, and making an immersive petrographic experience.
Multichannel acquisition of geological thin section. Different forms of polarization illumination can be used to highlight different features. Plane polarized light (PPL) shows overall crystal color, habit and pleochroism. Crossed polarized light (XPL) at multiple orientations allows for extinction angle and birefringence to be assessed. Circular polarization allows for maximum birefringence to be observed regardless of grain orientation. All channels are aligned using powerful computational algorithms during acquisition, making resulting data perfect for subsequent segmentation and analysis.
Automated machine-learning based mineral classification using a single ZEN Intellesis model, applied on two sandstone samples.
Both modal mineralogy and pore / grain sizes can be measured and automatically reported.

Polarization microscopy provides a broad set of challenges when preparing to build automated workflows for sample digitization. These unique challenges, broadly arise from the orientation dependence and can be tackled using a combination of specialized equipment, automation, image processing and machine-learning based analysis techniques. In this technology note we will give an overview of the advanced technologies developed to tackle these challenges, including automated multichannel acquisition, motorized polarizers and analyzers, and circular polarization. It will also cover how these techniques are integrated into ZEISS microscopy platforms, including the Axioscan 7 digitisation platform.
