LIGHT BEAM CONTROLS
The width of the light beam is controlled by the knobs on the side of the lamp arm nearest the bottom.
To move the light beam to the side of the
field of view as when using sclerotic scatter
or indirect illumination, the knob on the
back-lower part of the light tower is
loosened. Turn the light tower by the base
of the tower which has the beam with
control.
The light tower can also be tilted forward
by releasing the latch between the two light
beam with controls and tilting the tower.
The latch allows 5 degree increments of tilt.
This control can be useful for gonioscopy
and fundus examination.
