||The C-PH, a state-of-the-art N.A. 0.8 Phase Contrast condenser, is standard on
all Phase Contrast models. Used with EAP Phase Achromats for observations of low-contrast
or transparent specimens and living cells, the C-PH condenser incorporates phase annulus
rings for 10X, 20X, 40X and 100X objectives, as well as a Brightfield position.
The phase annuli are easily centerable with two knurled alignment knobs.
The condenser also features a built-in aperture
diaphragm and swing-out filter holder (Ř33mm). When ordered as an Upgrade Package (UP-PH3 or
UP-PH4), it includes three or four Phase Contrast Achromats, a centering telescope
and a green filter (FG-33), and comes in a wooden box.
