Using Eyepieces Incorporating a Micrometer
} When the eyepieces in use incorporate a micrometer, the accuracy of
the left-right focusing adjustment (diopter adjustment) can be improved
further.
1. Looking into the right eyepiece with your right eye, turn the top of the
eyepiece @ so that the micrometer in the field of view looks sharpest
(Fig. 42).
2. Looking into the right eyepiece, rotate the coarse and fine adjustment kn-
obs to bring the specimen and micrometer (cross lines, etc.) into focus.
3. Looking into the left eyepiece with your left eye, rotate the diopter adjust-
ment ring

to bring the specimen into focus.

For how to adjust the centering of the condenser, see page 12.

*
When using the U-SC3 swing-out condenser together with a 1.25X to 4X objective, fully open the condenser aperture
iris diaphragm and use the field iris diaphragm in the base as aperture diaphragm. With the 1.25X to 2X objectives, the
surroundings of the field of view may become dark.
} To obtain better illumination in camera recording using a 1.25X to 4X objective, use of the U-ULC-2 is recommended.
**
When the U-LC is used with an objective with an NA of 1.0 or more, the NA of the lighting becomes insufficient.
} When the U-LC is used, it is required to attach the auxiliary lens (page 35).
