Overview

The Nikon ECLIPSE Ci‑L plus is a refined upright biological microscope built for comfort and productivity during long observation sessions. Developed by Nikon with a strong focus on reducing operator fatigue, this model uses a smart Light Intensity Management (LIM) system that remembers and restores preferred LED brightness settings for each objective. This feature eliminates sudden fluctuations in illumination when switching magnifications, helping to ease eye strain.

Ergonomics is another highlight: the microscope’s design supports a natural posture with an adjustable eyepiece tube (tilt and extension), a height‑adjustable stage handle, and an optional nosepiece spacer to lower stage height. A built‑in status display shows key parameters — magnification, brightness, LIM status, and ECO mode — right at the base, so you don’t need to change your posture to check them.

Under the hood, the Ci‑L plus is equipped with a long-lifetime, high-luminance LED (eco‑illumination) that provides uniform, stable light across the field, while producing very little heat. The base also houses an image‑capture button that, when paired with Nikon’s recommended camera and NIS‑Elements L software, allows seamless acquisition without breaking focus. For efficient imaging workflows, the microscope can automatically adjust the scale bar on your screen in response to changes in magnification — ideal when coupled with a Nikon camera and software.

Beyond standard brightfield, the Ci‑L plus supports a variety of observation modes, including phase contrast, darkfield, simple or color polarizing, and epi-fluorescence (with optional attachments). Overall, it combines Nikon’s optical quality with user-centric features to make extended observations more manageable, precise, and reproducible.
