8. Operation
Note:
If, after installation, point-like objects are ap-
pear in the image, the light guide must be pulled
1 to 2 mm out of the coaxial illuminator. The
point-like objects are caused by the fibers of the
light guide.
The specimen is illuminated by the illumination
optics, the reflector and the macro-objectives
1x, 2x and 4x. The 0.4x macro-objective is not in-
tended for the coaxial illumination, because the
object field cannot be illuminated completely.
The light source is centered and yields a ho-
mogenous object field illumination of up to 22
mm field of vision. The cold light source KL2500
is used for fine adjustment of the light intensity.
It can be adjusted electrically and mechanically.
For electrical light control, the color tempera-
ture is changed. For mechanical light control,
the color temperature remains constant.
Note:
The LED (20.9) or (20.11) is green if the corre-
sponding lamp is operated in standard mode. If
the LED is red, the bulb life of the lamp is
reduced.
The KL2500 can be controlled using the rotary
knobs (20.8 and 20.12).
Please make sure that the KL2500 is connected
with the included cable on the rear side of the
stand.
For reducing remaining internal reflections, at-
tach the anti-reflex cap (27.1) to the objective
currently being used. Rotate it until ideal image
contrast is achieved. This only works in connec-
