Changing filters
Use the motorized fluorescent filter cube changer on
the microscope control panel:
Red light shows current filter cube selection
The filter cube turret contains three filters plus an
empty slot
GFP : cube for green fluorochromes
RED : cube for red fluorochromes
CFP/ : cube for far red fluorochromes
or cube for CFP (see Paula for details)
SCAN : empty slot
Notes:
The cube in the CFP/ position is normally the far
red cube, suitable for fluorochromes such as
TOTO-3 and Cy5
The SCAN position is used for confocal imaging
and for transmitted light observation through the
eyepieces
