1. General
1.1 Introduction
Thank you for purchasing this device. With this high-quality product, you have acquired a very
innovative system that offers you a unique, spatial perception and experience when viewing
microscopic specimens and significantly enhances your day-to-day work.
Please read this user manual completely and carefully before unpacking, and thus before using
the system for the first time. Within this document, the terms "system", "product" and "device"
are mostly used synonymously and always refer to the complete system as a unit with all asso-
ciated devices and assemblies listed under 1.3.1, unless otherwise stated.
3D Global Solutions GmbH reserves the right to make changes to its products, their documen-
tation or specifications without prior notice. All information and functions described in this doc-
ument refer to the device status (hardware & software) at the time of delivery ex-factory. Func-
tions or behaviour of any updates carried out subsequently are not described in this user man-
ual. The latest documents are available for download at www.3dgs.eu. Please check this page
from time to time for information on the latest changes.
All information given here has been carefully checked, but no guarantee can be given for its
correctness and/or completeness.
The datasheet supplied with the system contains all relevant technical data on the system and
is to be regarded as an integral part of this user manual. This user manual forms an integral
part of the device and must therefore always be kept available for reference and passed on if
the device is sold.
The type plate of the device contains various symbols whose meaning is described here:
Before using the device for the first time, read this user manual completely and
carefully, as it contains among other things important safety instructions.
The device may only be operated in closed rooms. For more information, please
refer to the “Safety” section starting on page 8 of this user manual.
1.2 Purpose of this document
The purpose of this user manual is to assist you in commissioning and operating the device. In
addition, this document is intended to draw your attention to possible risks during unpacking,
commissioning and use of the device, and to highlight measures for avoiding risks.
If you do not fully understand any points in the user manual or if you have any questions, please
contact the Support department at 3D Global Solutions GmbH. A lack of or insufficient
knowledge of this user manual will result in the loss of any liability claims against the manufac-
turer.
This user manual describes the special functions of the “SCALEREO-Desk” digital 3D video
microscope system with hardware and software version 01.02.2022. The system may be avail-
able in different versions with possibly different appearance or different functions. For this rea-
son, not all illustrations or functions described here may apply exactly to all available versions.

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.
