Development Overview

Biological microscopes are used in a wide variety of disciplines ranging from "cutting edge" biological and medical research institutes, universities, hospitals and laboratories.
Biological and medical high-end research utilizes versatile experiment techniques. Research microscopes need to offer high system expandability, superior optical performance and ease of use to satisfy these demands.
For Laboratory microscopes, comfort and durability are essential to reduce user fatigue and maintain performance during long-time observation.
In response to these needs, Nikon Corporation has developed the "ECLIPSE Ni series," a microscope series that advances system expandability and ease of use in addition to acclaimed optical performance; and the "ECLIPSE Ci series" in pursuit of comfort and durability.


[ECLIPSE Ni series]

1. Improved system expandability

  • Various motorized accessories
    To meet the need for more versatile experiment techniques, more motorized options, such as filter wheel, high-speed shutter and photoactivation unit, are available for the Ni series.
    The Ni-U is a manual main body, which can be partly motorized for users who need minimum motorization.
  • Choices of focusing system
    Motorized type Ni-E offers choices of focusing system, stage focusing - typical for upright microscope, or objective focusing which is effective for in-vivo imaging or multi photon microscopy.

2. World top class optical performance

In the current Eclipse series, Nikon adopted the "fly-eye" lens array built into the transmitted light illumination optics to ensure uniform brightness to both eyepieces and digital detectors. Nikon's proprietary noise terminator mechanism is valued to capture high contrast, high signal-to-noise images in fluorescence. In addition to these features, new objective lenses — CFI Plan Apochromat λ series — employ the latest techniques including Nikon's unique "Nano Crystal Coat" to realize high transmission rates, world top class NA (numerical aperture) and chromatic aberration correction across a broad wavelength range. The result is sharp, crisp images with high contrast and resolution.

3. Improved ease of use

We improved the ease of use because experiments are often conducted with eyes on the eyepiece lenses for prolonged periods, or in a darkened room.

  • Different-shaped switches to change the function are arranged around the focus handle, so switches can be identified even in the dark. Also, observation modes (Epi-fluorescence, DIC, etc.) can be changed easily by pressing buttons in front of the body. (Ni-E only)
  • A new camera control unit DS-L3 (sold separately) can be used as a microscope controller for comfortable operation via intuitive icons on the LCD touch panel. (Ni-E/Ni-U)
  • The image capture button has been added on the side of main body. Images can be acquired instantly while operating and observing images through the microscope. (Ni-E/Ni-U)

4. 3D ergo design

  • The main body, which has been designed with a "3D Curve" gives a stylish, modern look.

[ECLIPSE Ci series]

1. More eco-friendly

  • The innovative Nikon "fly-eye" lens array combined with power-saving, long-life, high-intensity LED illumination makes illumination brighter, more uniform and eco-friendly. (Three times brighter than that of our current model) (Ci-E/L only)

2. More comfort

  • Motorized model Ci-E for comfortable observation
    This is Nikon's first motorized model for laboratory use. Switching objective lenses is motorized with the condenser top lens motorized and synchronized to the objective selected, and brightness is adjusted to the level set by each objective lens to suit the users' preference. You can concentrate on observation without thinking about operations.
  • Image capture button function
    The image capture button is added on the side of main body for easy capturing while the eyes remain on the eyepiece lenses.
  • Adjustment mechanism to keep natural posture
    The angle of the eyepiece tube and the height of the stage handle can be adjusted to match the users' stature or observation posture. The Ci has various adjustment mechanisms to match all users.

3. More durable

  • Highly durable stage
    New stage incorporates a highly durable, scratch resistant ceramic coating designed to meet the needs of high volume users.
