TD_UserManual_SCALEREO-Desk_13xyyC Rev. 1.4 / 25.02.2022 7/ 29
1.3.3 Optional special accessories
The following optional accessories are currently available for the “SCALEREO-Desk” system:
•Wireless foot pedal
for controlling camera functions (magnification & focus), as well as for creating photo/video documentation
To purchase optional accessories, please contact your dealer or contact 3D Global Solutions
directly. We are also happy to offer additional accessories or specially developed customised
solutions.
1.3.4 Technical function
The stereo 3D camera system built into the desk microscope unit captures the microscope
specimens from two perspectives that are laterally slightly offset from one another. The auto-
matic focus system integrated into the SPU ensures ideal focussing of the cameras and 3D
alignment of the stereo images optimised for the current magnification factor. These signals are
processed in the SPU in real time and converted into a special 3D image format.
The processed 3D signal is displayed on the autostereoscopic (glasses-free) 3D screen and
can thus be perceived spatially by the user without having to wear special glasses. The display
is calibrated to the light colour of the microscope illumination and thus ensures natural colour
reproduction of the microscope specimens. The delay (latency) of the entire image processing
chain (from image acquisition through signal processing until screen output) is less than 80 ms.
The headtracking system integrated into the display housing allows the system to monitor the
current position of the user in front of the display and to continuously adjust the 3D image on
the display so that the user can move relatively freely in front of the display. The user just has
to maintain a viewing distance of approx. 55-80 cm to the display within a predefined viewing
area (approx. ± 22.5° to the centre axis of the display). This allows the user to maintain an
upright and thus healthy posture at all time when using the system.
Due to the headtracking camera technology used (“Time of Flight”), the user's face must be
clearly visible to the system and must not be hidden either visually (e.g. due to obstacles be-
tween display unit & user / scarf / hood / mouth/nose mask, etc.) or by a transparent cover (e.g.
protective glass pane between display unit & user / face shield, etc.).
If the user is not clearly recognised by the headtracking system, e.g. because the user is outside
the detection area or the face is covered, the system switches automatically to a 2D image
playback.
The headtracking system has various tracking modes and can also be paused or deactivated,
if required, so that e.g. the image on the display can be viewed temporarily by multiple people
at the same time (each in small, clearly defined areas).
The desk microscope unit has an integrated multi-segment lighting system (a combination of
coaxial & ring lighting segments) that very flexibly allows different lighting scenarios, each with
continuously variable luminous intensities.
The current image can be temporarily paused (“freeze”) or permanently saved for documenta-
tion purposes. The images or video sequences saved in this way can be copied to a USB stick
for further external use.
The whole system is controlled via a control unit (ControlBar), starting with camera control
(zoom & focus), lighting (mode & intensity) and toggling of the headtracking modes right up to
the image & video documentation.

Never connect or disconnect any cables at the SPU when the system is
switched on. The camera/illumination head of the desk microscope unit could
otherwise be irreparably damaged or destroyed!
To deinstall the system, follow all the above points, but in the reverse order.

3.3.2 System start
•Turn the mains switch on the back of the SPU, below the mains connection socket to 1
(ON) to make the system ready for operation.
•Briefly press the button on the front of the SPU to start the system.
•The SPU boots the system, loads all the necessary programs and visualizes the area
under the microscope on the 3D display.
•Note that the complete system start can take up to 40 seconds.
•Should the system not function as expected, first check paragraph 5 on page 27. Possi-
ble problems and their causes are listed there.
The system always starts with the settings that were in use before the last shutdown
of the system. If, for example, the tracking system was deactivated the last time the
system was used, it will also be deactivated after the system start and may have to
be started manually (see paragraph 4.5 / page 21)

4. Operation
4.1 Positioning of the specimens
Depending on the actual height of the specimens to be viewed under the microscope, the height-
adjustable camera/illumination head has to be brought into a suitable position.
To do this, use the turning device attached to the upper end of the rail. A scale on the front of
the rail shows you the ideal setting height for the respective specimen height.
•For flat specimens (printed circuit boards, etc.), the camera/illumination head can re-
main in the lowest position. => Scale: Arrow pointing to “0”.
•For tall specimens (e.g. parts of 15 cm height), the camera/illumination head should
be moved approx. 15 cm up => Scale: Arrow pointing to “15”.
Position the specimen centrally in the area under the camera.
4.2 Fundamental operating concept
The whole system is controlled via the ControlBar. The ControlBar is designed in such a way
that it can be individually optimised for the respective working method and positioned directly at
the workstation. The buttons are mostly self-explanatory and intuitive to use.
Some of the buttons have different functions, depending on how long the buttons are pressed.
The diagram below shows the basic assignment of the keys; in the case of a possible double
assignment, the respective functions are marked with
•SP (short press < 0.5 s), or
•LP (long press ~1 s)

4.3 Operation of the lighting
The SCALEREO-Desk system is equipped with a very helpful and variable
multi-segment lighting unit. In addition, the lighting can be steplessly
dimmed. All lighting settings can be changed with the lighting buttons on
the ControlBar.
4.3.1 Lighting mode
Use the middle button to switch through the different lighting modes until
you have found a mode that suits your application.
The following modes are available:
(the pictures show the camera/illumination head from below)
OFF All Central
Ring Left Right Middle Ring Right Ring All
4.3.2 Illuminance level
Adjust the illuminance level with the two buttons “LED+” and “LED-” until you have found an
illuminance level that suits your application.
In addition, you can use the two buttons “G+” and “G-” to adjust the gain of the camera and
optimise the image representation for your application.
The system was calibrated at the factory with the default settings for the illuminance
below and the display representation of "50% grey" was adjusted to match the col-
our temperature of the lighting (5700K).
Changing the illuminance settings may result in a change in the colour rendition on
the display.
Default values for calibration:
Mode: Ring All
GAIN: 50%
LED: 30%
Zoom: minimum

4.4 Operation of camera functions
The system is equipped with a very reliable and convenient automatic focus system. This auto-
matically performs an auto-focus adjustment with each zoom operation. This function not only
adjusts the focal point, or the plane of focus, but also optimises the alignment of the two stereo
images to each other, so that a natural and convenient 3D image is obtained on the 3D display.
Depending on the specimen surface and the selected zoom level, it may take a few seconds
until the automatic focus is correctly adjusted. It may also be necessary to optimise the image
with a manual focus correction.
4.4.1 Zoom
•A short press (< 0.5 s) on “Z+” or “Z-” manually activates an auto-focus without changing
the zoom level.
•A long press (~1 s) on “Z+” or “Z-” allows the zoom factor to be steplessly increased
(“zoom in”) or decreased (“zoom out”).
•The speed of the zoom function can be changed in the “Settings” menu and adapted to
your needs (see chapter 4.8.1 on page 24).
4.4.2 Focus
The depth of field of the system depends, among other things, on the current lighting and cam-
era settings as well as on the currently set zoom factor. If necessary, you can adjust the focal
point or the plane of focus manually:
•A long press (> 0.5 s) on “F+” shifts the plane of focus down.
•A long press (> 0.5 s) on “F-” shifts the plane of focus up.
•The speed of the manual focus function can be changed in the “Settings” menu and
adapted to your needs (see chapter 4.8.1 on page 24).
