Optical microscope ECLIPSE LV100N POL

for materials analysislaboratoryfor research

Product overview
The ECLIPSE LV100N POL LED and Ci-POL are polarizing microscopes designed for observation and analysis of birefringent anisotropic specimens. Nikon CFI60-POL optics support qualitative and quantitative polarizing microscopy workflows for eyepiece observation and digital imaging.

Applications
Mineralogy, petrography, materials science and analysis of optically active materials. Suitable for both transmitted and reflected polarizing observations, including conoscopic and orthoscopic techniques for composition and distribution studies.

Product highlights

• Combined diascopic (transmitted) and episcopic (reflected) illumination with simple changeover; LV-UEPI-N universal epi-illuminator option.
• LV100N POL LED: high colour-rendering LED with built-in 12V–24W PSU. Ci-POL: built-in 6V–30W halogen illumination.
• Extensive polarizing accessories: Berek, Senarmont and quartz-wedge compensators; DIN slot‑compatible centring nosepiece; rotatable graduated stage with mechanical stage option.
• Long focus stroke (30 mm) to accommodate tall or coarse samples.

Core features

• P-I intermediate tube with rotatable slider-type analyser (360°) and focusable, centrable Bertrand lens for conoscopic figures.
• Nikon CFI60 / CFI60-2 POL objectives: infinity optics, long working distance (LWD), high NA, strain-free POL objectives for high-contrast imaging.
• Uniform diascopic illumination using a fly‑eye optical design for full-field uniformity and digital quantification.
• Reversed objective mount with centring quintuple nosepiece (detachable) and DIN compensator slot.
