Focus in comfort. Comfort in focus.
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.
* Compared to the time required for adjusting the light intensity when switching among three different objective lenses.
Test was carried out by Nikon, using a previous LED-based microscope model.
Push the brightness control knob briefly to activate the LIM feature.

Low stage for effortless slide replacement
The height of ECLIPSE Si stage is 135 mm, which is about 50 mm lower than our conventional microscopes.
The lower stage design reduces the range of motion required to exchange specimen slides, and in turn this can reduce arm and shoulder fatigue.
Since the position of the stage movement knob is also lower, different areas on the specimen slide can be easily explored while resting your hands on the table.
The lever for opening and closing the specimen holder has also been designed to be ergonomic with an easy-to-operate size and shape.
Furthermore, the ECLIPSE Si features a 30% smaller stage compared to our conventional microscopes in order to optimise slide replacement.

Enables natural posture to be maintained throughout the entire microscope workflow
The inclination angle of the eyepiece tube is 45 degrees, which enables observation through the eyepieces while maintaining a natural posture. The low stage design also allows you to seamlessly switch from looking through the eyepieces to checking the slide placement on the stage without having to adjust your posture. An optional eye-level riser is also available to further tailor the height of the eyepieces.

Worry free focusing thanks to vertical stop
The ECLIPSE Si is equipped with a stopper that can be used to set the upper limit of the stage height.
The stage stops at the set height even when the focus knob is turned, thereby eliminating the risk of over-focusing and breaking the slides or damaging the objectives.
Specimen exchange and focusing can be performed with confidence, without worrying about the stage height.

Pursuing stress-free ease of use
We wanted to design a microscope that would eliminate fatigue incurred by frequent specimen exchanges and provide a more comfortable user experience. The ECLIPSE Si combines innovative features and intelligent design to minimize unnecessary body movements, saving time and reducing strain on the user even when examining a large number of slides.
Adjusting focus and moving the stage with one hand
The coarse and fine focus knobs are located on both sides of the microscope, making it possible to focus with either hand. In addition, the stage handle is positioned close to the focus knob, allowing users to easily adjust both the stage position and focus with the same hand.
With the stage movement and focus controlled by the same hand, the other hand can be dedicated to rotating the nosepiece or replacing the slides.
These features provide an efficient workflow even when examining a large number of specimen slides.

Blocks blue component in LED light
Since LED light contains a large amount of blue or short wavelength light, there is concern that prolonged observation may put a strain on the eyes.
The ECLIPSE Si offers an optional blue light blocking filter that can be placed on the field lens to remove the blue component of the LED light.
Automatically turning off illumination after a certain period of time
The ECLIPSE Si is equipped with an ECO mode which automatically turns off the illumination after a certain period of inactivity.
The length of the inactivity period is adjustable. With ECO mode, the ECLIPSE Si helps you save power without any effort.
Press and hold the brightness control knob to turn on the ECO mode.
Easily share images on-site and remotely
Capture specimen images for documentation or for real-time sharing with others by configuring the ECLIPSE Si (trinocular version) with a digital camera.
When the ECLIPSE Si is configured with the Digital Sight 1000 microscope camera (optional), images of specimens can be easily displayed on the monitor for simultaneous observation by multiple people, and recorded without the use of a PC.
Furthermore, by connecting the camera to a tablet PC*, images can be shared in real time with remote or off-site PCs and smart devices via a network.

*C-TB, C-TF, C-TT and C-TE2 tubes
Long-life LED with constant color temperature
The high-intensity, white LED light source, features a long life of up to 60,000 hours. Since the color temperature remains constant even when the brightness is changed, the color of the image does not change when changing magnifications.
Uniform brightness up to the periphery of the field of view
The illumination system features an integrated fly-eye lens which provides uniform brightness over the entire field of view.
Fly-eye lens
Blocking light from outside the field of view
The ECLIPSE Si is equipped with a field diaphragm that can be used to limit the illumination range for optimal observation and image acquisition.
Adjusting the field diaphragm suppresses the occurrence of flare and ghosting, enabling high contrast image observation.
During fluorescence observation, the range of photobleaching of specimens can also be limited.
