Advanced research and clinical upright microscope combining superb optics with optional motorized accessories for system expandability and flexibility
With its robust performance, bright and sharp optical system, flexible stratum structure and motorized options, the Eclipse Ni-U is the standard model in Nikon's advanced upright microscope series. It can support a wide range of observations, from clinical examinations to bioscience research.

Stratum structure for system expansion
Nikon's proprietary stratum structure enables simultaneous mounting of two optical paths on one microscope to support various applications.
This structure allows double layer mounting of an epi-fluorescence illuminator, a photoactivation unit and a back port unit, developed for the first time for upright microscopes to enable simultaneous photoactivation and imaging, and simultaneous multichannel imaging.
High-speed motorized accessories
Motorized options for the objective nosepiece, epi-fluorescence cube turret and shutter are available.
Supreme optical performance
Nano Crystal Coat technology
Employed for the first time in microscope objectives, this anti-reflective coating consists of nanometer-size particles.
It is based on semiconductor manufacturing technology and is also used for Nikon camera lenses.
The coating's coarse structure and uniform arrangement of particles in a spongy construction result in extremely low reflective indices.

CFI Plan Apochromat Lambda series objective lens
With remarkably high NA, greatly improved transmission in the long wavelength range thanks to Nikon’s proprietary Nano Crystal Coat technology, and chromatic aberration correction from 435 nm to 850 nm, these objectives are ideally suited not only for brightfield and DIC observations but also for fluorescent observations.
These lenses allow bright and clear image acquisition for a broad range of wavelengths from visible light fluorescence to near-IR imaging.
Their high-efficiency transmission means minimal excitation light can be used to reduce photo-damage to specimens.
Water dipping objective lenses
With a long working distance and high NA, these objectives provide excellent transmission in near IR wavelength range.
The axial chromatic aberration of CFI Apochromat NIR 40X/60X W has been corrected up to 850 nm, providing high-resolution images of minute structures in thick specimens during IR-DIC observation.
The CFI75 Apochromat 25XC W series and CFI Plan 100XC W also feature high NA andlong working distances. With chromatic aberration corrected in the IR region, these objectives are ideal for multiphoton excitation observation.
In addition, these lenses provide correction collars to compensate for temperature- and depth-induced spherical aberration, resulting in crystal clear images of areas deep within thick specimens.
Uniformly bright illumination
A built-in "fly-eye" lens ensures uniform and bright illumination of the field of view, from edge-to-edge, at any magnification.
Fluorescence noise elimination
Nikon’s proprietary noise terminator mechanism is employed in the epi-fluorescence cube turret and filter cubes.
The S/N ratio has been dramatically improved by thoroughly eliminating stray light in the filter cubes, allowing images of weak fluorescent signals to be captured with high contrast and brightness.
Ultimate ease of operation
Simple digital imaging
Images can be captured with Digital Sight cameras by simply pressing the image capture button located on the microscope base.

Absolute comfort
The ergonomic tube and stage handle height adjustment mechanisms allow comfortable viewing positions.
The space-saving microscope base enables users to maximize their work area. A simple remote control pad for easy operation of motorized accessories is also available.
