CFI Apochromat Lambda S Objective Series

Microscope objectives optimized for live cell and confocal imaging.

Lambda S Objectives employ Nikon’s unique Nano Crystal Coat technology, an antireflective coating that virtually eliminates internal lens element reflections across a wide range of wavelengths. It is particularly effective in reducing stray light reflections and flare in high angle (large NA) lenses, enabling very high transmission rates over a broad range of wavelengths extending from the ultraviolet to the infrared. Nikon’s exclusive Nano Crystal Coat employs multiple layers of extra-low refractive index coating, which features ultra-fine crystallized particles of nanometer size. This technology was developed for Nikon’s world-famous photolithography semiconductor manufacturing products and is now available for advancing the performance of microscope objectives.
