Simultaneous multichannel imaging

  • Ni-E
  • Ni-L

Ni-E (focusing nosepiece) configured with motorized epi-fluorescence illuminator, motorized condenser and motorized quadrocular tilting tube

The Ni’s flexible stratum structure allows the back camera port unit and the epi-fluorescence attachment to be mounted at the same time, enabling simultaneous image acquisition of two different wavelengths with each camera. This enables the capture of high-resolution images in the entire frame for each wavelength without dividing the CCD chip. The use of individual cameras for acquisition allows the user to tailor acquisition parameters for each channel independently, allowing acquisition of high-sensitivity FRET images.

Imaging of fluorescent-labeled specimens

  • Ni-E
  • Ni-L

Ni-L combination

In combination with a motorized nosepiece and a motorized epi-fluorescence cube turret, each unit is automatically controlled according to the camera settings such as exposure time, camera gain, and time interval, allowing fast, efficient image acquisition.

The motorized epi-fluorescence cube turret shutter, which helps to reduce photobleaching of specimens, is easily operated with a convenient Ni-L remote control pad.

Automated imaging of pathological specimens

  • Ni-E

Ni-E combination

With the Ni-E, optimal brightness can be automatically adjusted with objective changeover, eliminating the need for manual adjustment. By controlling the optical zooming of the motorized DSC zooming port for quadrocular tube, it is possible to capture images with the desired angle of field while maintaining the image quality.

Ni-E provides fully motorized microscope control

Microscope operations related to observation can be automatically controlled as previously set. The Ni-E is a fully motorized model that is efficient for experiments requiring comprehensive control of various devices, such as photoactivation devices and confocal systems.

Automatic adjustment with objective changeover

  • Ni-E

Condenser, aperture, field diaphragm and ND filter are automatically set to optimal positions according to the objective magnification in use. In addition, XYZ stage travel distance per handle rotation and parfocal distance deviation correction are automatically adjusted. Microscope settings can also be manually adjusted.

Reproducing observation conditions

  • Ni-E

Selected observation conditions can be designated to individual buttons, enabling changes to be made at the push of a button. This is particularly convenient when reproducing specific observation conditions.

High-precision motorized focusing

  • Ni-E

High-precision Z-focus provides accurate Z-position information required for use with confocal laser microscopes and supports automated Z-series acquisition. Individual coarse and fine focus knobs enhance ease of operation.

High optical performance

Nano Crystal Coat technology

  • Ni-E
  • Ni-L

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 D series

  • Ni-E
  • Ni-L

The high-refractive index glass used in the oil-immersion objectives provides uniform brightness and high image quality up to the periphery of a large 25mm diagonal field of view, enabling efficient acquisition of seamless stitched images and supports macro imaging of large samples. High transmittance and chromatic aberration correction over a wide wavelength range from 405 nm to 850 nm enable reliable quantitative data acquisition for intensity analysis of nuclear staining. These high NA lenses are ideal for brightfield and DIC observations, as well as fluorescence and confocal observations.

Water dipping objective lenses

  • Ni-E
  • Ni-L

CFI Apochromat NIR 40X W/60X W objectives with long working distances and high NA provide high transmission over the near-IR wavelength range. Axial chromatic aberration is corrected up to the near-IR range, enabling high-resolution images of minute structures of thick samples during IR-DIC observations.

CFI75 Apochromat 25XC W and CFI Plan Achromat100XC W objectives featuring high NA (1.10) and long working distance (2.00 mm at 25XCW, 2.50 mm at 100XCW) are corrected for chromatic aberration in the IR range. These objectives can capture crisp images of deep regions of thick samples by adopting a mechanism to compensate for changes in spherical aberration that occur at different temperatures and observation point depths.

Uniformly bright illumination

  • Ni-E
  • Ni-L

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

  • Ni-E
  • Ni-L

Nikon's proprietary noise terminator mechanism is employed in the epi-fluorescence cube turret and filter cubes. The S/N ratio is dramatically improved by eliminating stray light in the filter cubes, allowing images with weak fluorescent signals to be captured with high contrast and brightness.

High color rendering LED light source

  • Ni-L

The high color rendering LED light source built-into the Ni-L provides natural color reproducibility comparable to a halogen light source, as well as light uniformity, long life, and other advantages associated with LEDs, making it effective for observation of pathological specimens.

Ease of operation

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.

Most microscope controls can be operated with easy-to-reach buttons on the front of the Ni-E. Operation buttons on the microscope's sides are angled to allow intuitive touch-type operations during observation. Also, the microscope has a status display that can easily check the current microscope settings.

Ergo controller (Ni-E)

Simple remote control pad (Ni-L)

Remote controller

  • Ni-E
  • Ni-L

The simple remote control pad for Ni-L makes it easy to control the motorized accessories. An ergo-controller with similar operational feel to the actual microscope is also available for Ni-E, facilitating intuitive operation.

Compact design without a protruding lamphouse

  • Ni-L

The Ni-L has a built-in LED light source for diascopic illumination and the lamphouse does not protrude, so it is short in depth and compact, saving installation space.
