Transmitled light insert
Inste ad of a filter block, a trans m itted light insert can be used in
the PLO EMOPAK for n or mal transmitted light microscopy .
The micro sco pe c an thus be use d alte rnately for transmitted

TWin wavelength method
This method is u sed for rec ognit ion of small amount s of one
fluoroc hrome in the presence of relatively large quantiti es of a
seco nd. By su ccessive exc it atio n with two wavelengths , th e
specific
nuorescence ca n be observed se parately from the
other. Two differe
nt compon en ts can th en, for example, be
recognised inside one or in separa te cells.
