3-3 Selecting the observation method
Engage the mirror according to the observation method to set the
observation light path.
BF: Reflected light brightfield observation (ND filter can be built-in.)
This position is also used for the reflected light brightfield/
darkfield simultaneous observation, reflected light differential
interference contrast observation and reflected light simple
polarization observation.
DF: Reflected light darkfield observation
Slide the BF/DF selection lever a to select the observation method.
Slide the lever so that it comes to the click position.
If you observe the image by changing between the
brightfield (BF) observation and the darkfield (DF)
observation frequently, be sure to insert the ND filter
provided with microscope frame on BF side in order to
reduce the brightness when changed from DF observation
to BF observation. For attaching procedures, see
“Attaching the ND filter for darkfield observation" on page
