High-resolution, large-FOV objectives that are suitable for observation using a plastic cell-culture dish
CFI S Plan Fluor LWD 20XC and CFI S Plan Fluor LWD ADM 20XC objectives for biological microscopes are effective in research utilizing stem cells and drug design research. They are capable of a long working distance*1 and provide a high numerical aperture. These objectives provide clear images even in observation with plastic cell-culture dishes, which are frequently used in various types of research.
The CFI S Plan Fluor LWD 20XC is suitable for brightfield, fluorescence and DIC observation, and the CFI S Plan Fluor LWD ADM 20XC can be used for brightfield, fluorescence and phase contrast observation.
*1 Working distance: The distance from the tip of the objective lens to the observation target when the target is in focus. A long working distance has numerous advantages, such as prevention of contact with the sample when changing objectives.
