Selection (H)
By rotating the knob (H)
different apertures may
be selected.
Large
The large, round, homogeneous patch is suitable for routine
examinations through fully dilated pupils. In this position the
mirror remains in the forward position and the optics are diverged.
Intermediate
The intermediate patch is designed to reduce reflections when
entering a partially or poorly dilated pupil (3mm). It is also ideal
for closer inspection of particular fundal areas. The mirror and
optics stay in the mid position.
Small
This light patch is ideal for small, undilated pupils. The mirror
moves back and the optics automatically converge.
The Keeler Vantage Plus
has 3 light apertures which
offer maximum stereopsis.
When you select the
aperture the illumination
and viewing mirrors
automatically adjust for
maximum stereopsis.
