Generate Complete Petrographic Data

Digitize samples in multiple image modalities using optimized multichannel acquisition to generate a data rich description of your sample. Motorized plane and cross polarization allow you to analyze both pleochroism and birefringence, while circular polarization shows maximum possible birefringence regardless of grain orientation.

Unique Technologies for Automated Petrography

Rapid scanning of up to 100 slides in a single run
Automated scan performance for continuous 24/7 operation
Intuitive scan profiles with easy to use functionalities
Fast switching among brightfield and polarization imaging modes

More Technology Details

Composite multichannel acquisition of Berea Sandstone, showing brightfield acquisition (start of the video), circular polarized (maximum birefringence) acquisition (middle of the video) and the result of phase segmentation / advanced digital analysis (end of the video). Machine learning segmentation is used to classify pore (gold), quartz (light blue), Calcite (dark blue), Micas (red) and opaque minerals (green and yellow).

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
Intensely advanced scan speeds in all brightfield imaging modes

Visualize Complex Digitized Petrographic Data

Go beyond the standard petrographic microscope with the ZEN Pol Viewer display to navigate the rich petrographic thin section 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.

Applications

Plane Polarized Light (PPL)

Cross Polarized Light (XPL)

Circular Polarization

Circular Polarization

Multi-Channel Acquisition

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.

PPL-to-XPL

Full thin-section polarization images. This kyanite-bearing schist has been imaged as part of a digital thin section collection. The upper image shows a single PPL orientation, while the lower view shows the capture of the thin section in multiple XPL orientations. This allows a simulated stage rotation to observe and analyze extinction angles, with the full XPL variation over 90°.

Correlative Microscopy

Use ZEN Connect to intuitively build correlative projects that start with the data-rich, light microscopy environment from ZEISS Axioscan 7 Geo. Here additional phase and geochemical information from ZEISS Mineralogic becomes the next step in a petrological investigation. Sample shown is a granulite facies metagabbro from Scouriemore, North West Scotland.

Mineral Phase Analysis

The combination of ZEISS Axioscan 7 and ZEISS AI-based segmentation enables automated analysis across large numbers of samples. Easy machine learning segmentation allows you to label each mineral phase of interest using an intuitive painting interface and allows the software to build a model of the mineralogy across your entire sample.
Mineral Orientation Analysis

The optional PetPAT orientation analysis package turns entire thin sections into powerful mineral orientation maps. These datasets can be used in conjunction with mineral segmentation for detailed studies and used to generate grain size distribution data.

● Use XPL image stacks to calculate the angle at which any given pixel is at maximum or minimum luminance
● Use these data to allow the entire thin section to be mapped for orientation of mineral grains in transmitted light
