    Using the Filter

(Figs. 20 to 23)

}Use filters as needed to increase the accuracy of observation and photo-

micrography.
The 25LBD filter is especially recommended for observation and photo-
micrography where high light intensity is required because it achieves
the most natural color reproduction when the light source voltage is set
to maximum (provided that a long-life halogen bulb is used).

# After mounting the filter or when not using the filter, slide the light

shielding sleeve @ closed to prevent light from leaking from the
filter holder. (Fig. 20)

How to mount

To avoid putting fingerprints on the filter, hold it at the edges with both
index fingers and place it in an appropriate filter groove.

}The filter grooves ² are positioned obliquely to prevent flares.

First remove the stage center plate and then place a required filter while
confirming the filter grooves ² and ³. (Fig. 22)

How to remove

The filter is very hot right after use. Wait until the filter cools down
before removing it.

1. While holding the upper part of filter with your right index finger | and left

index finger

, pick up the filter to remove it. (Fig. 23)

2. If the filter is dirty (with fingerprints, grease, duct, etc.), wipe it clean with

tissue paper or clean cloth.
