Introduction to ZEN – Efficient Navigation
ZEN - Efficient Navigation - is the new software for the LSM Systems from Carl Zeiss. With the launch
of this software in 2007 Carl Zeiss sets new standards in application-friendly software for Laser Scanning
The ZEN 2008 Interface is clearly structured and follows the typical workflow of the experiments
performed with confocal microscopy systems:
On the Left Tool Area (Fig. 4/D) the user finds the tools for image acquisition, image processing and
system maintenance, easily accessible via 3 Main Tabs (Fig. 5/1). All functions needed to control the
microscope and to acquire images are bundled in the Acquisition Tools (Fig. 5/3 and 4). Arranged from
top to bottom they follow the logic of the experimental workflow. The area for viewing and interacting
with images is centered in the middle of the Main Application Window: the Center Screen Area.
Each displayed image can be displayed and/or analyzed with many view options available through "view
tabs” which can be found on the left side of the image. According to the chosen view tab, the required
view controls appear in View Control Blocks below each image. File management and data handling tools
are found in the Right Tool Area (see Fig. 4 and Fig. 5).
Color and brightness of the interface have been carefully adjusted to the typical light conditions of the
imaging laboratory, guaranteeing optimal display contrast and minimal stray light for high-sensitivity
detection experiments. The ZEN software is optimized for a 30" TFT monitor but can also be used with
dual-20" TFT setups.
Fig. 6
Basic and Pro Mode
A focus in the development of ZEN 2008 was to fulfill the needs of both basic users and microscopy
specialists. Both types of users will appreciate the set of intuitive tools designed to make the use of a
confocal microscope from Carl Zeiss easy and fast:
The Pro-Basic concept ensures that tool panels are never more complex than needed. In Basic Mode,
the most commonly used tools are displayed. For each tool, the user can activate Pro Mode to display
and use additional functionality (Fig. 6).
Fig. 7
ZEN Window Layout configuration
More features of ZEN 2008 include:
The user can add more columns to the Left Tool Area or detach individual tools to position them
anywhere on the monitor. To add a column, drag a tool group by the title bar (e.g., "Online
Acquisition") to the right and a new tool column automatically opens. To detach a tool, click on
the little icon on the very right end of the blue tool header bar (Fig. 7).
Another unique feature in Imaging Software is the scalable ZEN interface. This Workspace Zoom
allows adjustment of the ZEN 2008 window size and fonts to the situational needs or your
personal preferences (Fig. 7).
Setting up conventional confocal software for a specific experiment can take a long time and is
often tedious to repeat. With ZEN these adjustments have to be done only once – and may be
restored with just two clicks of the mouse. For each type of experiment one can now set-up and
save the suitable Workspace Layout. These configurations can also be shared between users.
For most controls, buttons and sliders, a tool tip is available. When the mouse pointer is kept
over the button, a small pop-up window will display which function is covered by this tool/button.
These are just some of the most important features of the ZEN interface. For a more detailed description
of the functionality for the ZEN 2008 software, please refer to the User Manual that is provided with
your system.
Setting up a new image document and saving your data
To create a new image document in an empty image container, click the "Single"
or the "Start"
button. The new document is immediately presented in the Open Images Area. Remember, an
unsaved 2D image in the active image tab will be over-written by a new scan. Multi-dimensional scans or
saved images will never be over-written and a new scan will then automatically create a new image
Alternatively you can create a new empty image document with the "New"
Button area or the "New" function in the File Menu.
button in the Action
Acquired data is not automatically saved to disc. Make sure you save your data appropriately and back it
up regularly. The ZEN software will ask you if you want to save your unsaved images when you try to
close the application.
There is no "image database" any more like in the earlier Zeiss LSM software versions.

New image document in the Open Images Ares
Advanced data browsing is available through the File Browser (Ctrl-F or from the File Menu). The File
Browser can be used like the WINDOWS program file browser. Images can be opened by a double-click
and image acquisition parameters are displayed with the thumbnails (Fig. 9). For more information on
data browsing please refer to the detailed operating manual.

Turning on the lasers
• Open the Laser Tool in the left tool area (always the first in the list) and activate the lasers you need
for your experiment (Fig. 10). Remember, the argon multi-line laser has to first be put to standby for a
5 minute warm-up before it changes to on.
• Zeiss recommends operating the Argon multi-line Laser at a tube current of about 6 A (∼50 %
output). This is the best compromise between laser stability/power and laser life-time. (tube-current
control can be found in Pro Mode).

Configuring the beam path and lasers
• Click on the LSM button.
Choosing a configuration
Simultaneous scanning of single, double and triple labeling:
− Advantage: faster image acquisition
− Disadvantage: Eventual cross-talk between channels
Sequential scanning of double and triple labeling; line-by-line or frame-by-frame:
− Advantage: Only one detector and one laser are switched on at any one time. This reduces crosstalk.
− Disadvantage: slower image acquisition
• Open the Imaging Setup and the Light Path tool in the Setup Manager Tool group to access the
hardware control window to set-up the beam path.
The open Light Path is shown in Fig. 14.

Track Configurations window
Settings for multiple track configurations in Channel Mode
Multiple track set-ups for sequential scanning can be defined as one configuration (Channel Mode
Configuration), to be stored under any name, reloaded or deleted.
The maximum of four tracks with up to 8 channels can be defined simultaneously and then scanned one
after the other. Each track is a separate unit and can be configured independently from the other tracks
with regard to channels, Acousto-Optical Tunable Filters (AOTF), emission filters and dichroic beam
The following functions are available in the List of Tracks panel in the Imaging Setup Tool (Fig. 15,
Fig. 16 and Fig. 17).
Switch track every
Tracks are switched during scanning line-by-line. The following settings can be changed
between tracks: Laser line, laser intensity and channels.
Tracks are switched during scanning frame-by-frame. The following settings can be
changed between tracks: Laser line and intensity, all filters and beam splitters, the
channels incl. settings for gain and offset and the pinhole position and diameter.
Frame Fast
The scanning procedure can be made faster. Only the laser line intensity and the
Amplifier Offset are switched, but no other hardware components. The tracks are all
matched to the current track with regard to emission filter, dichroic beam splitter,
setting of Detector Gain, pinhole position and diameter. When the Line button is
selected, the same rules apply as for Frame Fast.
Add Track button
Remove button
An additional track is added to the configuration list in the Imaging Setup
Tool. The maximum of four tracks can be used. One track each with basic
configuration is added, i.e.: Ch 1 channel is activated, all laser lines are
switched off, emission filters and dichroic beam splitters are set in accordance
with the last configuration used.
The track marked in the List of Tracks panel is deleted.
A click on this arrow button will move the selected track (highlighted in light
grey) one position upwards in the list box.
A click on this arrow button will move the selected track (highlighted in light
grey) one position downwards in the list box.
Scanning an image
Setting the parameters for scanning
• Select the Acquisition Mode tool from the Left Tool Area (Fig. 18).
• Select the Frame Size as predefined number of pixels or enter your own values (e.g. 300 x 600) in the
Acquisition Mode tool. Click on the Optimal button for calculation of appropriate number of pixels
depending on objective N.A. and λ.
The number of pixels influences the image resolution!
Fig. 18
Acquisition Mode tool
When using an Axioskop 2 FS MOT, make sure you set the correct objective manually in the
Acquisition Mode tool. This ensures correct calibration, calculation of pinhole and Z stack
optimization, etc. The Axioskop 2 FS MOT does not automatically detect the objective lens.
Adjusting scan speed
• Use the Scan Speed slider in the Acquisition Mode tool (Fig. 18) to adjust the scan speed.
A higher speed with averaging results in the best signal-to-noise ratio. Scan speed 8 usually produces
good results. Use speed 6 or 7 for superior images.
Choosing the dynamic range
• Select the dynamic range 8 or 12 Bit (per pixel) in the Bit Depth pull-down in the Acquisition Mode
tool (Fig. 18).
8 Bit will give 256 gray levels; 12 Bit will give 4096 gray levels. Publication quality images should be
acquired using 12 Bit data depth. 12 Bit is also recommended when doing quantitative measurements or
when imaging low fluorescence intensities.
Setting scan averaging
Averaging improves the image by increasing the signal-to-noise ratio. Averaging scans can be carried out
line-by-line or frame-by-frame. Frame averaging helps to reduce photo-bleaching, but does not give quite
as smooth of an image.
• For averaging, select the Line or Frame mode in the Acquisition Mode tool.
• Select the number of lines or frames to average.
Adjusting pinhole size
• Select the Channels tool in the Left Tool Area.
• Set the Pinhole size to 1 AU (Airy unit) for best compromise between depth discrimination and
detection efficiency.
Pinhole adjustment changes the Optical Slice thickness. When collecting multi-channel images, adjust
the pinholes so that each channel has the same Optical Slice thickness. This is important for
colocalization studies.
