New Objective For Nikon Physiostation Microscope

The new Nikon Instruments Fluor 20× Water Dipping objective is used exclusively on the Eclipse E600FN "PhysioStation" upright-focusing nosepiece research microscope. The CFI Fluor 20× Water Dipping Objective is part of a set of objectives especially useful in physiology and brain research where the objective is actually "dipped into" the exposed living tissue or brain slice. The objective provides excellent resolution and bright fluorescent signals with a numerical aperture (N.A.) of 0.50, while having excellent transmission in the infrared (IR) wavelengths. The working distance of the Fluor 20× objective is 2 mm, which is consistent with the other objectives included in the set. In addition, the E600FN comes with a parfocal distance adjustment lever, which can eliminate discrepancies that sometimes occur when users switch between a low magnification water-dipping objective to a higher magnification water-dipping objective.
