The PH3 phase ring is designed for use with PH3 condenser annuli and is the appropriate phase ring for high-magnification (typically 40×–100×) phase contrast imaging. Phase contrast at 100× with NA 1.40 delivers exceptional detail in living cell imaging — revealing internal cell structures, organelle dynamics, and bacterial morphology with high contrast without staining or fixation. The plan apochromat correction ensures that this objective also performs at the highest level for fluorescence, DIC, and brightfield imaging, making it a versatile choice for labs that need phase contrast capability alongside fluorescence at 100×. The RMS thread mount fits standard microscope nosepieces; an M27 adapter is available upon request for Zeiss Axio series microscopes with M27 nosepieces. This unit is offered in excellent, like-new condition at a significant discount to the new list price of $6,500.
