10. Use of the microscope (Brightfield transmitted light)

10.1 Light intensity adjustment

Operate on the light intensity dial
scope and to increase or decrease the illumination intensity. (Fig.
10)
• Only for B-383LD: the switch located at the back of the
microscope operates to turn on the transmitted light (po-
sition "I") or the reflected light (position "II"). Turn on the
microscope for transmitted light by turning the switch
to "I".

10.2 Adjust the interpupillary distance

Hold the right and left parts of the observation head using both
hands and adjust the interpupillary distance by turning the two
parts until one circle of light can be seen. (Fig. 11)

10.3 Diopter adjustment

1. Look into the right eyepiece with your right eye only, and fo-
cus on the specimen.
2. Look into the left eyepiece with your left eye only. If the image
is not sharp, use the diopter adjustment ring
sate. (Fig. 12)
• Highpoint eyepieces allow the use also to glass wearers.
• NOTE: For optimal parfocality, we recommend using your
glasses during normal microscope use.

10.4 Coarse focus tension adjustment

To adjust the tension according to personal's needs, rotate the
ring using the provided tool (Fig. 13). Clockwise rotation in-

creases the tension.
• NOTE: If the tension is too loose, the stage could go low-
er by itself or the focus easily lost after fine adjustment.
In this case, rotate the knob in order to increase the ten-
sion.
