Changing Filters and Dichroics
Changing Excitation and Emission Filters
The 25 mm filters are held in position by a 25 mm filter ring. This ring is already
screwed into each filter socket. Identify the position (1-8) where you want to
place or replace the filter and unscrew the ring using the provided filter wheel
ring wrench.
The filters need to be mounted so that the surfaces are facing in the correct
direction. Both excitation and emission filters have an arrow marked on the side
of the filter to indicate which direction the filters should face.
Make sure that the arrow on both the excitation and emission filters is pointing
towards the sample (towards the dichroic mirror) when placed in the filter
wheels.
