Condenser discs* for contrast techniques
Both condensers can be fitted with discs for
various contrast techniques (HF = Brightfield,
DF = darkfield, PH = phase contrast, ICT = trans-
mitted light interference contrast) (See Fig. 15).
5-position condenser turret for HF, DF, 3 PH po-
sitions (15.1).
8-position condenser turret for HF, DF, 3 PH
positions, 3 ICT positions, or HF, 3 PH positions, 4
ICT positions (15.2). Whole- and quarter-wave
compensators (15.3 or 17.6) can also be used
instead of ICT prisms for polarized light micro-
scopy.
