Overview
Ideal as an educational microscope or for routine laboratory use for biology, geology and industry, the Eclipse E200 POL incorporates Nikon’s acclaimed CFI60 infinity optical system to provide a high quality, compact and easy-to-use polarizing microscope at a modest price. Because the E200 POL’s design is based on the Eclipse E200 biological microscope, it shares the same objectives and uses many of the accessories created for higher-grade Eclipse series microscopes, enabling more advanced polarizing microscopy.
 
Key Features:
Refocusing Stage. The unique Refocusing Stage makes specimen handling quicker and easier. The stage can be instantly dropped, just by pushing it down, to exchange specimens or oil the slide. It returns to the original position as soon as the hand is removed.
Comfortable Viewing.The Siedentopf-type eyepiece tube — P-TB binocular or P-TT trinocular — is inclined at 30° to ensure a natural posture for more comfortable viewing.
Easy Lamp Replacement. The microscope comes with a unique top-access 6V/20W halogen illuminator. Simply slide open the lens-unit cover to replace the lamp.

CFI60 Infinity Optical System
The CFI60 optical system combines Nikon’s renowned CF optical design with infinity corrected optics to overcome the limitations of the traditional infinity design. CFI60 optics provide longer working distances and higher NA’s to deliver startlingly clear images at any magnification because chromatic aberrations are corrected over the entire field of view.

Robust, Vibration Resistant Construction
A solid one-piece casting from arm to base, plus a substantial 188.5mm width, provides greater rigidity and resistance to vibrations. The E200 POL is a synthesis of great Nikon optics and solid, vibration-resistant construction

Conoscopic Observation
The intermediate tube with a Bertrand lens lets you observe conoscopic images. This feature is perfect for uniaxial or biaxial crystal identification, or for evaluation of other optical qualities such as optical signs.

Photomicrography Capabilities
Photomicrographic systems can be mounted on the trinocular eyepiece tube to add documentation to your system. This system is easier to use than ever before, featuring auto exposure, 1% spot, and 35% integrated average metering and user-friendly simple controls built into the main unit.

L-IM Epi Illuminator
Incorporating a 12V/50W lamphouse, this new epi-illuminator provides more than sufficient brightness for reflected light polarizing applications.

Filters
The daylight-type blue filter assures correct color rendition required for sample evaluation, while the GIF filter is used for retardation measurements and contrast adjustment.

Compensators
Senarmont and Quartz Wedge compensators are available for quantitative retardation measurement.
