As of May 2021, ZEISS AxioVision will be classed as End of Support. End of Support means that ZEISS will no longer provide hotfixes to address operating system updates, security issues and functionality. We may be able to offer ad hoc service and support, however this will be dealt with on a case-by-case basis. For AxioVision Particle Analyzer systems only, the End of Support date is August 2022.
Please note, only the very latest version of Axiovision 4.9.1 is compatible with Windows 10, meaning an AxioVision PC failure that uses an operating system older than Windows 10 may also require a software upgrade.
ZEN is the successor programme to AxioVision, and provides users with a variety of important benefits that were previously unavailable.
ZEN - or ZEISS Efficient Navigation - is our modular imaging software that lets you control all light microscope systems from ZEISS, allowing you to operate all of your devices with the same convenient interface, while arranging operating elements in a way that follows your work flow. ZEN software comes with a flexible choice of modules and a variety of innovative features, making it your indispensable image analysis partner.
Even in the basic version ZEN offers countless functions for day-to-day work with your microscope. Thanks to its modular concept, however, the software guarantees you other advantages too: you can tailor ZEN precisely to your requirements and only need to learn to work with the functions you actually need. You will find the optimal ZEN module for every task here.
Use ZEN to create meaningful microscope images. Give two-dimensional multichannel images additional depth of field, for example, or acquire temporal and spatial information together with your image.
With ZEN Multi Channel image acquisition module you create images with multiple channels. To do this, with widefield systems you combine any number of fluorescence channels with images in transmitted light, e.g. phase contrast, according to your requirements. A special feature here is that you can select your dyes from the integrated database. This already contains data sets for more than 500 fluorochromes and can be expanded as required.
For each fluorescence excitation wavelength, the relevant channel is acquired with the optimal exposure time. An independent exposure time and microscope setting can also be assigned to each channel. The advantage: you structure your experiments flexibly and perform even highly complex multichannel experiments simply.
ZEN Z Stack module helps you to acquire axial image stacks on your ZEISS microscope with motorized focus drive. The image acquisition program controls the Z-drive of your stand in precisely the right increments and synchronizes it with acquisition. ZEN can calculate the increments fully automatically, if required, or you can allocate them manually.
A special feature here is that from now on you create your Z Stacks with graphical support. This assistance is even available to you dynamically during acquisition. The size of your experiment, which is saved in a compact .CZI file, is limited only by the travel range of your system and the minimum increment.
With the Extended Focus module you generate images with extended depth of field from previously acquired Z-stacks. The ZEN module extracts sharply imaged details from existing images at different focus positions and combines them to create a new image. The advantage: you always have maximum depth of field in all regions of your images in transmitted light, reflected light and fluorescence contrast.
With the optional ZEN Tiles & Positions module and a motorized stage you scan your specimen automatically, making it possible to analyze large areas. A large, virtual overview image can be generated in this way from numerous individual images. This allows you to navigate over the specimen like a map and zoom easily into any regions of interest. Tiles & Positions and ZEN align the individual images precisely in relation to one another, providing the optimal basis for further analyses.
A special feature here is that a software wizard helps you to mark positions on multiwell plates, multi-chamber slides, slides and dishes interactively and locate them with a click of your mouse.
Would you like to plan complex experiments in advance, but retain complete control at all times? From now on ZEN will help you do this! Using the Experiment Designer module you will even be able to create images in several combined image dimensions with just a few clicks of your mouse, and after only a short training period. You plan combinations or repeats of your image acquisition tasks. such as time series, Z-stacks, tile/multiposition images and channels, in a clearly visualizable form using experiment blocks.
Repeated steps can be achieved very easily using loops, and pauses or interactions can be defined if your experiment extends over a long period and requires interactive intervention. The Experiment Designer supports an almost unlimited number of blocks in your experiments, which can naturally be saved and reloaded at any time. You plan, ZEN controls.
With the ZEN Time Lapse module for widefield systems you control your microscope, camera and imaging software from ZEISS. This allows you to document dynamic processes in your specimens with a compact image sequence. ZEN controls the exposure setting for your microscope here with millisecond precision. With the Time Lapse module, damage is no longer caused to specimens as a result of unnecessarily long exposure times – an important requirement for your quantitative analyses of living specimens.
Your most impressive images can be exported at any time into common video formats, such as AVI or MOV, for demonstrations and publications. The advantage: images are acquired with maximum speed and are only limited in size by the free space available on your hard drive.
With the Manual Extended Focus module you use ZEN to create images without being restricted by your microscope's depth of field. The software module extracts the sharp details at different focus positions from the interactively acquired Z-stacks and combines them into an image with maximum depth of field. Using the live image display, additional images can be added to the intermediate result.
The advantage: you always have maximum depth of field in all regions of your images. This even applies irrespective of the contrast technique used – whether transmitted light, reflected light or fluorescence, thanks to our wavelet algorithm.
With the Autofocus module for widefield systems you determine the optimal focus position for your specimen in transmitted light, reflected light and reflected light fluorescence. ZEN "learns" the ideal position during your everyday work on the light microscope and is therefore trained continuously with regard to correct focusing. No calibration procedure is required for this and the focus is recorded automatically for all objectives and contrast techniques.
The additional advantage for you: in the case of images that are acquired over time or at different positions, the system continually refocuses automatically.
This ZEN module is ideal if your specimens no longer fit into the image field. With Panorama you create high-resolution overview images from individual images. The software puts the images together with pixel precision. The advantage: even images that have been acquired offset from each other can be joined precisely using ZEN and Panorama. This means that important details from the individual images of your microscope specimen are recorded in a single image.
A special feature here is that you can use the live image as a 'joystick' and therefore acquire the individual images even more quickly.
With these powerful additional modules you can display fluorescence signals with even greater contrast or visualize image stacks in 3 dimensions. ZEN therefore creates the best possible conditions for your experiments and publications.
The Colocalization module can be used to unmix the overlapping signals of different fluorescence channels.
To do this, the ZEN software makes use of modern methods, such as the automated threshold value method of Costes et al. Meaningful results on the colocalization of proteins can be obtained as a scatter plot, image and data table.
If you only want to analyze certain areas of the image, you can simply mark the corresponding region directly in the image and scatter plot. Spectral Colocalization for ZEN then supplies the data both for the whole image and the selected regions.
Of course you can also export your measured values in CSV format and process them further using a spreadsheet.
Due to the optical properties of the microscope system, light from the areas above and below the focal plane also enters the image. This means that fine structures on the specimen can no longer be picked out.
It is precisely here that the 3D Deconvolution software module starts, by calculating out of focus light back to its place of origin. The distorted specimen structure unfolds and is displayed more sharply. This technique also reduces any image noise that may be present, making a decisive contribution to the first-class image quality of your image stacks and 3D models.
With 3Dxl you can display multi-dimensional image stacks in 3D. The ZEN module processes up to 8 different channels and works seamless with other image dimensions such as time (“4D”) or multiple tiles. Highlight is its ability to handle really large images (hundreds of gigabyte) efficiently and smoothly.
You can position a three-dimensional model interactively according to the view that you require and provide it with annotations, coordinates and scaled axes. It goes without saying that 3Dxl also provides you with tools for the interactive measurement of distances and angles. Would you like to present or publish the result afterwards? If so, simply export the images and animations into common image formats, such as TIF, JPG or AVI.
Analyzing and Interpreting Image Data
ZEN provides important information on your microscope specimens interactively or fully automatically. Besides size and volume information, this also includes detailed data on cell physiological processes
Would you like to generate automatic measurement procedures simply yourself? The ZEN Image Analysis module makes it possible for you to do this, even without programming knowledge. With our measurement program wizard you tackle even complex measurement tasks yourself in just a few minutes. Once created, the programs are always available to be used for an unlimited number of images. You retain full control over the measurement process at all times.
Each step can be changed interactively before it is performed. Even processes that run automatically can be easily interrupted if necessary, allowing you to adjust the settings to your requirements. If desired, you can of course also use the Image Analysis module to export all your measurement data simply in the Excel-compatible CSV table format and process them further as you wish.
Measure microscopic structures interactively. Generate gray value profiles of cell organelles. Trace the contour of a cell nucleus with your mouse to determine its area. Count cells simply by clicking on them.
With the ZEN and the Interactive Measurement module you define yourself which of the 90 plus morphological parameters available are measured in your images. The Contour tool, for example, allows you to determine the area, diameter and perimeter of a cell simultaneously. You perform a comprehensive and precise analysis of the cell in a single operation, even in the online image. For each tool you can specify which measurement results you want ZEN to show in your image.
The Interactive Measurement module also enables you to present your measurement data impressively in the form of a table, list or graph. ZEN 2011 saves your measurements together with the image data in the new CZI file format. This means that you can export your measurement data at any time in Microsoft Excel-compatible CSV format for documentation or further analyses.
