Nano Crystal Coat guarantees optimum brightness in multi-color fluorescence live-cell imaging. Nikon’s exclusive ultra-low refractive index coating technology “Nano Crystal Coat” used in the manufacture of professional SLR camera lenses, is now incorporated into the new Plan Apochromat λ series objectives. This technology enables remarkably high transmission throughout a broad range of wavelengths, from UV to the near-IR region. Offering bright, sharp and high contrast images, these lenses are perfect for multi-color fluorescence live-cell imaging, particularly for fluorescent dyes with longer wavelengths that are less phototoxic to living specimens.
