Newly developed LED illumination and exclusive CFI infinity optics deliver clear, bright images at every magnification.
Designed for years of high quality use, the Eclipse Ei is an upright microscope with outstanding optical performance combined with elegant ergonomic touches. The Ei ideal as an educational or student microscope incorporates Nikon's exclusive CFI infinity optical system and an high-intensity LED eco-illumination system that is IR-free, virtually eliminating eyestrain for users. In addition, advanced Nikon BE2 Plan Achromat objectives have been designed especially for the Ei with excellent optical corrections and very flat optical performance. This means clear, bright images at every magnification.
Key Features
Enhanced LED Eco-Illumination
The Ei 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
Standard 30 Degree Eyepiece Tube
Siedentopf-type eyepiece tube inclined at a comfortable 30 degrees. Interpupillary distance of 47-75mm is largest in its class. 180 degree rotatable eyepoint adjustment to accommodate operators of different builds.
High-Eyepoint Eyepieces
Wide 20mm field of view with built-in diopter adjustment on both eyepieces provides easy parfocality adjustment. Eyepieces lock to prevent theft, damage, or vandalism.
Upper Limit Stage Stop
Allows the user to set the upper limit of the stage movement so objective does not hit the specimen slide, protecting both from damage.
4 Position Reversed Nosepiece
Microscope comes standard with 4x, 10x, 40x, and 100x objectives. 20x and 60x Dry objectives are also available.
Compact Design
Utilizing a lightweight design, the Eclipse Ei was created with a small footprint that is compact and easily fits into a storage cabinet.
BE2 Plan Achromat Objectives
Specially designed for the Ei, CFI BE2 Plan objectives provide a bright, high contrast and flat-field image over the entire 18mm field of view.
CFI45 Infinity Corrected Optical SystemThe Eclipse Ei incorporates Nikon’s revolutionary CFI Infinity Corrected Optical System with advanced specifications for crisp, bright images at every magnification at a modest price.
Anti-mold designAnti-mold paint and an anti-mold tablet are used in the objective lenses, eyepiece lenses and eyepiece tubes to prevent mold forming in high-humidity environments.
Nikon Manufactured GlassTo further assure quality control of the lenses and design versatility, Nikon manufactures its own glass from raw silica to the final optical coatings.
Optional TechniquesNewly designed accessories for simple phase contrast and darkfield are available.
