Replacing the excitation filter, barrier filter, and dichroic mirror
The excitation filter, barrier filter, and dichroic mirror can be removed from the filter cube and
replaced with different parts.
When handling these parts, put on gloves and do not touch the surface of filters and mirrors with
bare hands. And be careful not to let dust or fingerprints get on them.
• Replacing the excitation filter
The excitation filter is secured by a screwed type holding ring to the filter cube.
1 Rotate the holding ring in counterclockwise direction
to remove it.
2 Replace the excitation filter and secure it by the
holding ring.
Check and see the arrow mark on the rim of the
excitation filter is directed to the dichroic mirror side
when attaching the excitation filter.
If a filter made by other manufacturer is used, check
and see the indication on the rim of the filter.
• Replacing the barrier filter
The barrier filter is secured by a screw type holding ring to the mounting plate on the upper side of
the filter cube.
1 Press the latch to inside and detach the mounting plate
and barrier filter together.
2 Rotate the holding ring to remove it from the
mounting plate.
3 Replace the barrier filter and secure it in reverse order.
Check and see the arrow mark on the rim of the barrier
filter is directed to downward (dichroic mirror side)
when attaching the barrier filter.
If a filter made by other manufacturer is used, check
and see the indication on the rim of the filter.
• Replacing the dichroic mirror
The dichroic mirror is fixed with a flat spring and a mounting part inside the filter cube.

2 Pull the mounting part upward to remove it. (It is
clamped with latches on both sides.)
3 Remove the flat spring and dichroic mirror.
