OPERATION PROCEDURES

(4) Decentering the slit beam

With the Model SL-3E, the illumination can be moved from the parafocal position with the
microscope by loosening the centering control. The illuminated image then would move away
from the center of the microscope's field of view. It is of particular benefit in indirect retro-illu-
mination techniques. To return the slit image to the center of the field of view, tighten the slit
centering knob firmly.

(5) Oblique illumination

Oblique illumination is used for sectional or fundus examination by use of a contact lens, etc.
(i.e. gonioscopy). As the inclination lever is released, and the arm is pulled towards you, the
illumination unit inclines by 5° steps to 20°. Since the illumination unit may contact the
patient's face, proceed carefully.
