CFI Plan Fluor Series for Phase Contrast

Superb optical design provides exceptional resolution under multiple techniques

CFI plan fluor series objective lenses for phase contrast microscopy. These objectives are multi-purpose; they can be used for brightfield, fluorescence and phase contrast observations. They facilitate high-quality fluorescence observation and provide exceptionally detailed resolution of minute structures in phase contrast observation. This is especially desirable because the use of phase contrast to find the desired portion of the specimen before switching to fluorescence observation is an excellent way to minimize fluorescence photobleaching.
