Filter Lever Selection (I)
By rotating the lever (I),
different filters may
be selected.
Blue Circle
Cobalt blue filter for fluorescein angioscopy.
White Circle
Clear light – Select the clear with no filter when inspecting a
specific pathology and a brighter, whiter light is desired.
Green Circle
Red Free filter – this filter reduces the red light, so blood will
appear black, silhouetted against a dark background.
Diffuser
This unique extra wide beam of diffused light permits a more
relaxed technique during more challenging fundus examinations.
Beginners may also find this aperture particularly helpful since
the alignment between the headset, the condensing lens and the
pupil, in order to achieve a full lens image, is not as critical as
with the conventional beam.
