Rapidly Digitize Massive Collections
Fully automated acquisition, coupled with ZEISS quality, ensures consistently high image quality, even when processing thousands of samples. Load and run 100 thin sections in minutes with minimal user overhead for set-up, sample naming, and detection.
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.

Collaborate across Borders with Your Virtual Microscope
Upload acquired data from your virtual petrographic microscope to cloud platforms, allowing for global image storage and transfer alongside intuitive collaboration. Digitize entire collections to allow for online and remote teaching. Integrate this data into existing courses to enable virtual field-trips, supporting and augmenting traditional modes of learning.

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.
AI-Based Mineral Classification
Automated machine-learning based mineral classification using a single ZEN Intellesis model, applied here on two sandstone samples.
Both modal mineralogy and pore / grain sizes can be measured and automatically reported.
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°.
Close up of a single biotite grain within a granite sample. Sample has been imaged in multiple PPL orientations in order to observe the full range of pleochrosim as the sample is rotated through 180° relative to the polarizer.
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 creates the Petrography Analysis Toolbox, or PetPAT. Easy machine learning segmentation enables you to label each mineral phase of interest using an intuitive painting interface and allow the software to build a model of the mineralogy across your entire sample.
The powerful PetPAT orientation analysis package turns entire thin sections into 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
