Enhanced LED Eco-Illumination
The E200 incorporates a high-intensity LED eco-illumination system* that is IR-free, virtually eliminating eyestrain for users. Eco-illumination boasts a long lifetime of 60,000 hours, and reduces the need for frequent lamp changes. LED illumination also offers very low power consumption and heat generation and eliminates color temperature changes that occur with halogen light sources. *Halogen version also available
Crystal-clear Images with CFI60 optics
The CFI60 optical system combines Nikon's renowned CF optical design with infinity optics to overcome the limitations of the traditional infinity design. CFI60 optics provide longer working distances and higher NA's, and deliver startlingly clear images at any magnification because chromatic aberrations and curvature of field are both corrected over the entire field of view when the field number is 20mm. Nikon developed new dedicated CFI E Plan Achromat objectives exclusively for the E200. Also, you can use other higher-grade objectives available for the Eclipse series whenever your laboratory situation calls for it.
Ergonomic Design Ensures Comfortable Operation
Nikon has incorporated the ergnomic innovations of its other laboratory and research-grade Eclipse series microscopes. For example, the focus knob and the stage handle are located equidistant from the operator, permitting one-handed operation in a natural posture without twisting the shoulders. Because these controls are low positioned, you can operate the microscope while resting your arms comfortably on the desk. In addition, the low-profile stage makes exchange of specimen slides easy, while the low inclination angle eyepiece tube provides comfortable viewing.
Improved Eyepiece Tube
The Siedentopf-type eyepiece tube is inclined at 30° to ensure comfortable viewing in a natural posture. Designed for use by operators with different builds, this eyepiece tube has a narrow minimum interpupillary distance of 47mm, while the eyepoint height can be raised 34mm when interpupillary distance is 64mm by simply swinging the front part of the eyepiece tube up 180°. For extremely tall users, eye level risers are available to customize the microscope.
The E200 eyepieces feature a wider field of view for a microscope of this class and are available in 10x (F.O.V. 20) and 15x (F.O.V. 12) types. These eyepieces also feature built-in diopter adjustment that allows the operator to adjust diopters separately for the right and left eye easily. In addition, these eyepieces accept measuring reticles that will always be in sharp focus with the specimen. The eyepieces can be locked, preventing theft and eliminating the possibility of damage during transit.
Unique Refocusing Stage Eliminates the Need to Refocus Manually
The Refocusing Stage eliminates the need to refocus the image manually, making specimen handling safer and easier. In this unique design, the stage can be instantly dropped by pushing it down to exchange specimens or oil the slide, then returns to the original position as soon as the hand is removed. The wide stage surface can accommodate two slide glasses at the same time.
Upper Limit Stopper
When using short-working-distance objectives such as 40x or greater, you can set the upper limit of the stage movement so that the objective doesn't hit the specimen slide, protecting both from damage. Thanks to this feature, even novices or operators who need to change slides often can perform their job easily and quickly. The limit height can be set in two levels using a stopper bolt - either at the standard position or 2mm lower. This feature is very useful for standard slides and is not recommended when extraordinarily thick specimens are used.
A reversed-type nosepiece creates more space at the front of the stage, making handling of specimen slides fast and easy. In addition, the CFI60 optical design eliminates extra optical elements in the nosepiece for enhanced image sharpness. Another advantage of CFI60 objectives is that their increased objective lengths and longer working distances provide more working space around the nosepiece.
Adjustable Binocular Tube Reduces Strain
With this option, users can adjust not only the eyepiece tube tilt angle, but the eyepiece length to suit their build, eliminating discomfort and strain during long hours of observation.
Up to two eye-level risers can be mounted to raise the height of the eyepoint - 25mm each for a total of 50mm.
Robust, Vibration Resistant Construction
One-piece construction from arm to base, a stage design where the up/down mechanism is located in the base, plus a wide footprint of 188.5 mm across the back all provide greater rigidity and resistance to vibrations, contributing to superior images.
Anti-mold Agents Resist Mold Growth
Mold is a formidable enemy of microscopes. Before you know it, mold can begin growing on the interior optical surfaces of the microscope and ruin performance. Using anti-mold paint, plus anti-mold agent sealed at critical places inside the microscope, the Eclipse E200 is designed to resist mold growth. In tests, an anti-mold treated unit was able to resist the growth of mold for three consecutive years at an average temperature of 30° C (86° F) and 80% humidity.
