Eclipse Si

Nikon has designed the ECLIPSE Si to meet the rigorous demands of professionals who spend hours using the microscope. The ECLIPSE Si is ergonomically designed to enhance operational efficiency. This powerful instrument helps you to stay focused for longer by reducing the strain on your body. The ECLIPSE Si is the new standard in microscopes, expanding the possibilities of exploring the micro world.

Pursuing efficient workflow

The ECLIPSE Si has been developed with the primary goal of reducing fatigue during microscope usage. The ECLIPSE Si eliminates unnecessary adjustments and enables efficient and comfortable operation. The ergonomic design also enables natural posture, even when carrying out repetitive tasks.

Maintaining comfortable brightness when switching magnifications

Objectives with different magnifications transmit light to varying degrees. Therefore, light intensity must be adjusted every time the user changes the objective. In addition, when switching from high to low magnification objectives, the sudden increase in brightness often causes eye strain. The ECLIPSE Si features the intelligent Light Intensity Management (LIM) which automatically remembers and sets the light intensity level for each objective. The LIM feature reduces up to 40% of the time spent on adjusting light intensities*. With the ECLIPSE Si, users can increase comfort and save time even when the routine requires frequent magnification changes.

Ergonomically designed to reduce strain on eyes and body during long- term observation

  • The intelligent Light Intensity Management (LIM) Feature automatically remembers and reproduces the light intensity level for each objective,maintaining the appropriate brightness when switching magnifications
  • The low stage design reduces arm andshoulder fatigue when changing Specimen slides
  • The Stopper, Which Sets the upper limit of the stage height,eliminates the risk of damage to the slide and objective when changing samplesand focusing
  • Equipped With an LCD screen that displays the magnification, illumination, etc.
  • The Unique diascopic fluorescence illuminations method enables fluorescence imaging without mounting an epi-fluorescence attachment
