ALL PUPIL II by KEELER
4.2 HEADBAND ADJUSTMENT
Comfortable Fit
Adjust the Height and Size Adjusters (A and B) so that the Indirect is supported comfortably, as
shown in figs 1 and 2.
Ophthalmoscope Angle Alignment
Position the Brow Bar (I) such that the Binocular Block (H) is set on the optical axis.
The Brow Bar (I) may be correctly positioned by loosening the Brow Bar Adjusters (F). When in
the correct position secure by tightening (F) as shown in fig 3.
Position the All Pupil II as close to the eyes as possible for maximum field as shown in fig 4. by
using the Optics Hinge Adjuster (L).
Interpupillary Distance Setting Control (J)
Because the eyes are dissociated, particular care must be taken to ensure the optics (eyepieces)
are set properly in front of each eye.
Always set the Aperture Control Lever (D) to the large light patch for this exercise.
Place an object, approximately 40cm from the face and centre it horizontally in the light patch.
Then, close one eye. Slide the Interpupillary Distance Setting Control (J) of the open eye
(located directly under each eyepiece) so that your object moves into the centre of the field,
keeping the object in the centre of the light patch. Repeat for the other eye.
