The Nikon Eclipse LV 100 POL is a polarizing light microscope designed for transmitted (diascopic) and reflected (episcopic) polarized light microscopy. The microscope is intended primarily for the observation and photomicrography of stones, rocks, minerals, and high-polymer materials. The Eclipse LV 100 POL belongs to Nikon's Eclipse family of upright microscopes and is classified as a metrology and inspection instrument.[5][3][4]

The Eclipse LV 100 POL uses a 12V-50W halogen lamp with a fly-eye lens design. A built-in DC transformer is standard, and a 12V-100W type is optional with an external power supply. NCB11 and ND8 filters are built-in.[4]
The focusing stroke is 30 mm. Coarse adjustment is 14 mm per rotation, fine adjustment is 0.1 mm per rotation, and the minimum reading is 1 µm increments.[4]
The microscope uses CFI P Achromat objectives at 4x, 10x, 20x, 40x, and 100x, and CFI LU Plan Fluor EPI P objectives at 5x, 10x, 20x, 50x, and 100x. The latter are made with eco-glass free of lead and arsenic.[4]
Yes. Diascopic (transmitted) and episcopic (reflected) polarized light observations are possible. The LV-UEPI universal epi-illuminator is required for episcopic illumination, and a changeover switch on the microscope body selects between the two modes.[3][4]
