Adjustable focusing target
If the lamp cable (81) is connected, the fixation lamp burns as
soon as the power supply switch is activated, then the focusing
target (86) is visible.
The fixation target can be brought into any position by moving
the bearer's arm (82). This permits uninterrupted observation
through the microscope and simultaneous guidance of the
patient's eye to any desired position. This is especially advan-
tageous in examining the fundus.
It's a condition, that the patient's eye is correctly positioned at
the headrest's height marker (85).
Ametropia of the patient from +10 D to -15 D (83) can be
corrected (84). Steady fixation of the eye is maintained as
accommodation and convergence are avoided.
