Place the dichroic mirror in the excitation filter half’s slot. The surface of the
dichroic mirror with the beamsplitter coating must face
DOWN
.
Figure 5 The dichroic mirror is inserted into the excitation filter half.
2.5. Step
5
Align the emission filter half with the notch on the excitation filter half as shown in
Figure 6. Alternate tightening between the two assembly screws taking care not
to allow movement of the dichroic mirror.
Check the orientation of the dichroic mirror by looking into the excitation and
emission sides of the filter cube. The reflective (beamsplitter-coated) side should
be visible through the excitation side of the cube.
