Replacing the barrier filter
The barrier filter is fixed to the filter attaching plate at the upper part of the filter cube with the screw-in type
filter retaining ring.
1. Press the latch inward and remove the
barrier filter with the filter attaching plate.
2． Turn the filter retaining ring and remove it
from the filter attaching plate.
3． Replace the barrier filter with the desired one
and fix it by reversing the steps shown above.
Attaching direction of the barrier filter
When attaching the barrier filter, check that the
arrow on the filter ring points the dichroic mirror
(downward).
* When attaching a non-Nikon barrier filter, ask the manufacturer the attaching direction in advance.
Replacing the dichroic mirror
The dichroic mirror is fixed in the filter cube with the flat spring and mirror fixing part.
1. Remove the barrier filter with the filter
attaching plate.
2. The mirror fixing part is fixed to the cube
with the latch on both sides. Lift the mirror
fixing part upward to remove it.
3. Remove the flat spring and the dichroic
mirror.
4. Checking the attaching direction, place the
desired dichroic mirror as the original mirror
has been.
Attaching direction of the dichroic
mirror
To identify the reflection face, a dichroic mirror
has either of the following features: The one
edge of the dichroic mirror is obliquely cut, or
an L-shape arrow is marked on the side of the
dichroic mirror.
• Dichroic mirror with obliquely-cut edge
Place the mirror as the obliquely-cut edge
faces downward so that the obliquely-cut
edge matches the bottom surface of the filter
cube.
• Dichroic mirror with L-shape arrow
Place the mirror as the L-shape arrow points
the bottom side (opposite side from the
surface that contacts with the flat spring).
5. Attach the flat spring in the direction it holds
both of the edges of the dichroic mirror.
6. Attach the mirror fixing part and the barrier
filter as they have been.
* When attaching a non-Nikon dichroic mirror, ask the manufacturer the attaching direction in advance.
