grounded mains in room.
The Separating Transformer can be installed in patient environment in accordance with IEC 60601-
1 standard.
SOCT Copernicus+ is connected to computer using USB cable. This cable is electrically
separated using optocouplers. It provides additional safety, when computer and SOCT
Copernicus+ device are connected to two different power supply sockets with different ground
potentials. Video signal and synchronization signal are transferred to computer using coaxial
cables, which are electrically separated from SOCT Copernicus+ device providing even more
safe solution.
No user serviceable parts inside SOCT Copernicus+ device. Light source is included inside device.
Removing of covers can be done only by Manufacturer or Authorized Personnel.
The maximum power of light radiation available outside covers
Is less than 1020(±3) microwatts providing safe operation of the device.

service staff.
During the whole period of use, SOCT Copernicus+ does not need any special maintenance
procedures. The outside surfaces of device should be cleaned using mild cleaning solvents.
Only a soft cloth can be used for cleaning. During cleaning it has to be assured, that no water gets
inside the device.
The forehead rest and chinrest are parts that routinely have contact with patient. The forehead and
chin rests should be cleaned between each examination with an alcohol prep swab.
The main lens of the device should not contact the patient's eye. It comes with a lens cap to cover it
when not in use. Lens may touch the eyelashes during normal use. You should clean it to remove
dust and oily smudges occasionally to ensure a true tomogram images are obtained. You may use an
alcohol prep swab or cotton swab dipped in isopropyl alcohol. (You may use dedicated optical lens
cleaner.) Wipe dry with a soft, non-lining cloth or tissue. If the lens inadvertently contacts the
patient's eye, clean it before proceeding with the examination.
Periodically one has to check if there are no mechanical damages to the device, damages to any of
the cables and fuses.
5. Device Overview
SOCT Copernicus+ uses spectral domain optical coherence tomography method to obtain
3-dimensional cross-section images of a human retina. The device produces a laser beam,
which is focused on a human retina. The light that reflects from internal structures of a retina
is then interferometrically analyzed by the device. The raw data is processed by a computer to
obtain images of retina cross-section.
