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.
