ZEISS Axioscan 7

Your Unique Automated Petrographic Microscope for Digitization, Quantification, and Collaboration

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.

Unique Technology for Polarization Microscopy

A Variety of Super-fast Imaging Modes

The innovative motorized stage and image acquisition system allows automatic switching between different brightfield imaging modes to adapt to the different requirements of your applications. All data processing occurs inline to allow for optimized datasets of a manageable size ready for analysis, transfer or distribution once data acquisition finishes.

  • Improved sample detection and focusing
  • Circular and linear polarization now available
  • Intensely advanced scan speeds in all brightfield imaging modes

Visualize Complex Digitized Petrographic Data

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.

Circular Polarization

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.
