(Fig. 4)
}The ND filter is interlocked with the brightfield (BF) light path selecting so it
can be engaged or disengaged according to the mirror selector lever @.
The ND filter makes it possible to reduce glare when darkfield (DF) is
switched to brightfield (BF).

driver into the hole ² on the left side of the reflected light illuminator.
2. Now the interlocking is released and the ND filter knob (Fig. 3 |) is active.
