5. Setting up and using the Vantage Plus
Interpupillary Distance Setting Control (S)
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 Selection (H) to the large light patch for
this exercise.
Place an object, perhaps the thumb, approximately 40cm from the
face and centre it horizontally in the light patch. Then, close one
eye. Using the thumb and forefinger of the opposite hand, slide
the P.D.Control (S) 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.
Obtaining a fused image
Ensure that a singular, fused image is obtained as follows:
Mirror Angle Control (J)
The light is positioned vertically into the upper two thirds of the
field of view by rotating the spindle (J) located on either side of
the binocular block.
Head Dimmer Switch (T)
Turn the illumination on by rotating the headband dimmer (T)
in an anti clockwise direction.
