2 .2 Installing Dichroic Mirrors into the Cairn Filter Cube
To fit your dichroic mirror into the Cairn Filter Cube remove each of the
four screws that secure the two halves together. You will then be able
to gently pull the two halves apart. There is one steel locating rod in
each half of the cube to ensure the correct alignment when it is
reassembled. Once the two halves of the cube are seperated place the
dichroic mirror (active side down) into the rectangular recess. Then
simply reassemble the cube and tighten the screws.
2.3 Inserting the Cairn Filter Cube into the Optosplit II
The Cairn filter cube is designed to be easily accessible in order to
facilitate quick and easy changes of filter sets. Access to the filter cube
mount is gained by removing the access panel using the two handles
to pull gently and firmly. The filter cube mount will now be visible. The
mount attached to the rear of the Cairn Filter Cube is designed to mate
with the bracket on the internal wall of the Optosplit II so that the small
handle on top of the cube will be facing out. Once the Cairn Filter Cube
is mounted successfully replace the access panel using the two
handles.
