Nikon introduces the ECLIPSE Ci-L plus biological microscope, which helps reduce eye strain and is comfortable to operate

set. 28, 2021

TOKYO - Nikon Corporation (Nikon) is pleased to announce the release of the ECLIPSE Ci-L plus biological microscope, which eliminates the need for light intensity adjustment after changing magnifications and has an ergonomic design that takes into account the physical strain incurred during extended observations.

Development Background

Long term microscope users know all too well the issues of back and neck strain along with eye fatigue associated with operating and observing specimens under a microscope every day. To reduce these common fatigue problems, Nikon has designed the ECLIPSE Ci-L plus biological microscope with the intent of eliminating unnecessary operator movements while maintaining the high optical performance of the existing model, the ECLIPSE Ci-L. The ECLIPSE Ci-L plus enables users to concentrate on their observations and helps reduce fatigue associated with repetitive microscope operation.

Release Overview

Product Name ECLIPSE Ci-L plus biological microscope
Release Date September 30, 2021

Main Features

1. Help reduce eye strain by preventing sudden light intensity changes after changing magnifications

The Ci-L plus has a LIM (Light Intensity Management) feature that records the light intensity level of the LED illumination for each objective. The recorded light intensity is automatically reproduced when changing magnifications, eliminating the need to readjust the light intensity. This contributes to reducing eye strain by preventing sudden changes in brightness.

2. Ergonomic design contributes to reducing physical strain

The Ci-L plus’ ergonomic design makes intuitive operation possible, and enables the user to observe while sitting in a natural posture. The optional Ergonomic Binocular Tube allows adjustment of the inclination angle and extension of the eyepiece tube. The height of the stage handle, which is maneuvered frequently, is also adjustable. This allows the handle to be positioned at the optimal height for each observer, helping to reduce strain on the user’s body and allowing for more comfort during extended observations.

* The angle and extension of the eyepiece tube cannot be changed for the trinocular tube and binocular tube.

3. The front panel display enables confirmation of magnification and illumination status at a glance

A built-in display shows the objective magnification and the illumination brightness level. The position and design of the display enables users to easily view the display without changing their posture during observation. The Ci-L plus has been designed with a focus on operability.

4. Scale bar adjustment linked to nosepiece rotation for more efficient observation

When the Ci-L plus is used in combination with a microscope camera and NIS-Elements imaging software, as recommended by Nikon, the scale bar displayed on the PC monitor automatically adjusts with the magnification when the nosepiece is rotated, improving efficiency during observation.

*Camera and NIS-Elements are not for clinical use.

5. Automatic shut-off with ECO mode

The Ci-L plus is equipped with an ECO mode, which automatically turns off the illumination after a certain period of inactivity, saving electricity and preventing the illumination from being left on.
