OPERATION
12. The angle between the illumination system and the

the slit lamp arm. Refer to figure-17.
14. Magnification is altered by rotating the Magnification
Dial on the Microscope Assembly. Refer to figure-16.
SLIT LENGTH
The Slit length is adjusted by rotating the Slit Length
Dial. The dial has five stops for adjustments. They
are 0.6, 5.8, 9, 13.5mm diameter and continuous
1.5 to 12.0mm. They index into place. Refer to figure-18.

and are color coded to indicate the active filter. Refer
to figure-18. The color coded index stops are as
follows:
Blue dot = Cobalt Blue
Red dot = Heat Absorbing
White dot = Open
Green dot = Red-free
SLIT ROTATION
Slit Rotation is achieved by grasping the Slit Width/
Rotation Knob and twisting the slit body to the left or
right. The degree of rotation is indicated by the Slit
Rotation Scale above the slit body. Refer to figure-19.
