A Indications
instrument and operating
A. Lamp bulb
The tungsten lamp bulb is centered ex-works to obtain an
optimal illumination. The 'H-S' marking on the centering base-
cap indicates a genuine Haag-Streit spare part.
The light beam from the pre-centered bulb passes through the
condenser, the slit diaphragm and the illumination lens, before
it is directed to the patient's eye by the oblique mirror.
A. Regulating the brightness
The brightness of the slit light illumination can be varied by
means of
• the knob on the power supply which adjusts the intensity of
the slit illumination
• the 10 % grey filter on the upper part of the illumination unit
of the slit lamp
