Adjusting The Eyebase; Focusing / Diopter Adjustment - Leica ULTRAVID HD-PLUS Manual De Instrucciones

ADJUSTING THE EYEBASE

To set the eyebase, adjust the binoculars at
the hinged joint. The left and right fields of
view must merge and produce a single circu­
lar image.

FOCUSING / DIOPTER ADJUSTMENT

With the Leica Ultravid binoculars the central
focusing ring (4) is used to set the focus for
variously distant objects.
Compensation for individual defective vision
for viewing without eyeglasses is made using
the diopter ring (4), which is normally locked
(Figure A). To unlock the two rings the diopter
ring is pulled up (Figure B). Now, the central
focusing ring only effects the focus of the left
optical system, the diopter ring only that of
the right system.
