Nikon's Eclipse FN1 is a special purpose upright microscope developed from the ground up to meet the rigorous demands of electrophysiological research. Never before has an electrophysiological microscope allowed you to go so deep into your specimen with such clarity and contrast. That's because the FN1 fixed stage microscope has a completely redesigned optical system that includes the world's first water dipping objective with depth-induced aberration correction. The new microscope optics deliver longer working distances, slimmer profiles, better approach angles, and aberration-free images from the visible to infra-red region.

Open Design Provides Maximum Customization

By inserting a spacer between the body and the arm, you can raise the microscope height 10-30mm to facilitate large specimen observation.

Multiple Noise Reduction Features

The FN1 features an ON/OFF mechanism for the filter turret, optical path changer, magnification changer and the condenser filter changer to reduce vibration related noise.

Streamlined Operation

The focus knob and field diaphragm ring are located on the front part of the microscope base and there are no cumbersome outside belts, so operation is easy when using a fixed stage.

Safe and Easy Objective Changeover

Objectives mounted on the sliding nosepiece can be raised when switching magnifications thus preventing the objective from colliding with the manipulator or the chamber.

World's First Water Dipping Objective with Depth Induced Aberration Correction

The new Plan 100xW objective (NA 1.1, W.D. 2.5mm) is the world’s first water dipping lens with a correction ring.

Powerful 16x Objective Lens

The new CFI75 LWD 16x 0.80 NA objective features an industry unique working distance of 3.0mm and a 45° manipulator approach angle.

New Objectives Provide Ideal IR-DIC Imaging

A new set of physiological water dipping objectives have been developed for the FN1 featuring longer working distances of up to 3.5mm, with slimmer profiles, 45 degree approach angle for easy access of manipulator patch needle placements, special coated top lenses to prevent bubbles and new axial chromatic aberration correction for visible to near infra-red imaging.

Easy Insertion of Microelectrodes

The simple and slim I-shaped body has no projection on the body other than the focus knob, so there is more space in the working area for your experiment.
