Epi-fluorescence observation widens inspection range—including 365 nm UV excitation
Diascopic illumination capability and various observation methods such as brightfield, darkfield, simple polarizing and DIC. Epi-fluorescence observation, including 365 nm UV excitation, is also possible (L300N/L300ND/L200ND only).
Highly beneficial in inspection of semiconductor resist residues and organic electroluminescence displays
Motorized mercury fiber illuminator Intensilight for Epi-fluorescence observation
A motorized mercury precentered fiber illuminator is employed.
Lamp centering and focus adjustment are not necessary, even after lamp replacement.
The light source can be placed away from the microscope, reducing heat near the
microscope and preventing defocusing.
Variable light intensity and shutter control provide excellent flexibility.
The lamp has an average lifespan of 2000 hours.
Four times brighter than conventional Diascopic observation
The L300ND employs a new light source and advanced optics to provide four times brighter illumination for Diascopic observation.
CFI60 optics offer long working distance and high NA
Nikon’s original CFI60 optics offer both image brightness through high NA and wider sample range and access with long WD.
Provides clear, high-contrast brightfield images by minimizing flare.
The "fly-eye" lens array, which provides uniform illumination throughout
the visual field, is employed for darkfield illumination optics, allowing
remarkably bright, high-resolution darkfield images.
