ZEISS ZEN - Smart Aquisition

Smart Acquisition

Make your most complex experiments a success

Operate every one of your devices with the same convenient interface. Smart Setup, the intelligent control center, will automatically generate the settings for you, regardless of the microscope types. Aiming for reproducible experiments? So long as you have one raw image from a previous acquisition, a simple click lets you replicate the exact experiment precisely. You will find plenty of other smart automation, some guide you for rare events detection, and others assist you with hardware calibration.

ZEISS ZEN - Quantitative Processing

Quantitative Processing

Obtain reliable and reproducible results

More than 180 image processing tools help you transform and manage your data. Simply search the keyword of your intended method, e.g., kymograph or deconvolution, ZEN will lead you straight to it. ZEN will read the metadata of the input image, then display only the logical processing steps, and optimize the default parameters automatically. You can even process images from other platforms using third-party import tools. With a dedicated workspace, you can also batch process multiple images with ease for quantitative and unbiased results.

ZEISS ZEN - Powerful Visualization

Powerful Visualization

Interact with your big data confidently

Quickly generate a huge 2D tile scan with multi-channels at high magnification, and smoothly zoom in and out with a simple mouse scroll, just like using a map application on your smartphone. Having 200 GB of cleared mouse brain data? Just load it in ZEN – you will be amazed by the speed and clarity of the various 3D rendering methods. Powered by arivis ImageCore technology and efficient use of system resources, you can view your large 3D images even on regular consumer hardware.

ZEISS ZEN - Effective Analysis

Effortless Analysis

Gain insight into your research efficiently

Image analysis is essential to extract meaningful information from your microscopy images, via digital tools of segmentation and registration. ZEN addresses this with the simple and modular Bio Apps. Each Bio App is optimized for one type of application, e.g., cell counting or confluency measurement, with tailored segmentation settings and streamlined data presentation. The wizard-based ZEN Image Analysis module guides you step by step to create your unique measurements.

ZEISS ZEN - Unique Correlative Microscopy

Unique Correlative Microscopy

Combine perspectives across scales and modalities

ZEN overlays, navigates, and organizes your multimodal data. Spending days painfully locating synapses between two special neurons for the ultrastructural information? You can substantially improve your efficiency by combining the large field of view of a widefield fluorescent microscope and the high resolving power of a field emission electron microscope. ZEN lets you quickly overview the whole slice with fluorescent markers, identifying and relocating ROIs for EM imaging.

ZEISS ZEN - Secure Storage

Secure Storage

Stay confident when dealing with complex data

ZEN stores each of your valuable experiments with all its metadata.

The .czi file format is Bio-Formats compatible and can be read directly by ImageJ, and much other third-party software. Export your data into OME-TIFF (Open Microscopy Environment) to further facilitate cross-platform image data exchange.

To manage massive amounts of data, ZEN provides a server-based central platform to store and organize your raw data and manage user access right; while ZEN Data Explorer grants browser-based access from anywhere.

Simplified Access to Endless Possibilities

ZEN software provides a comprehensive end-to-end solution for any microscopy user, continuously evolving to address emerging life science applications with added features, e.g., automated smart acquisition, intuitive image analysis, and cloud-based data management. However, the increased capabilities also make the ZEN ecosystem complex.  With ZEN version 3.6, you get simplified options that make the numerous capabilities of the software more accessible. Many  ZEN modules show great synergy  and have been frequently combined to get your specific job done. Using that as the guiding principle, we have  consolidated  all the  powerful software functionalities  into a  simple set of acquisition, toolkit, and application packages tailored to your experiments. The packages come with a substantial price saving compared to the individual modules, so you can get more value for your investment.

    Large Data Handling​

    Bigger data. Faster processing.​
    With ever-increasing data sets, large data handling remains a key topic for microscope users. The ZSTD lossless compression can now be set as default for image acquisitions, leading to higher file transfer rates and optimized data storage. Furthermore, algorithms for maximum intensity projections, tiles stitching, and image pyramids generation have been significantly accelerated.​

    Stitching in Direct Processing​

    Stitching in Direct Processing​

    Faster and more automatable image pre-processing​
    The largely popular workflow tool Direct Processing has received another addition to its toolset. With ZEN 3.8 you will be able to include stitching directly into your automated acquisition workflows, while simultaneously benefit from performance gains by algorithm optimization and parallel processing.​
