5 Acquiring Images
WARNING!
Only use objective lenses provided by
Heidelberg Engineering
The incorrect use of objective lenses on the
SPECTRALIS camera, or the use of unauthorized
objective lenses, may result in the patient's retina
being exposed to hazardous laser light.
WARNING!
The Ultra-Widefield lens may touch the patient's
skin during the acquisition
Dirty device parts can transmit pathogenic germs
causing infections.
Disinfect the Ultra-Widefield lens with disinfectant
wipes before and after each examination.
Observe the instructions of the disinfectant wipes
manufacturer.
The focus range for a properly-focused image
acquired with the Ultra-Widefield objective lens
is significantly larger than with the SPECTRALIS
standard objective lens
Therefore, the displayed “Focus” value in the
“Settings” section is not reliable and may vary
significantly from the patient’s actual refraction.
Please note that only the central internal fixation light
and the external fixation light are available for Ultra-
Widefield imaging. The nasal, temporal, superior,
and inferior internal fixation lights are not available
when the Ultra-Widefield lens is mounted.

5.1.1 Available Acquisition Modes
To select an acquisition mode, turn the filter wheel either to “A” or
to “P” .
▪ If you select “P” , the acquisition mode is a cross-polarized mode.
In this mode, the central artifact caused by lens reflections is
reduced. In HEYEX, all images acquired with the filter wheel
position “P” are labeled with “XP” for cross-polarized.
