Nikon CFI Apochromat Lambda S LWD 20X Water Immersion Objective | MRD77200

The Nikon CFI Apochromat Lambda S LWD 20X Water Immersion Objective (MRD77200) is part of Nikon’s advanced Lambda S series — specifically designed for stem cell research, drug discovery, and high-content cell screening workflows. The combination of 0.95 NA and long working distance (0.99–0.9mm adjustable) enables high-quality imaging through plastic cell-culture dishes as well as standard glass coverslips, eliminating the need to transfer cells to glass for high-resolution observation. The Apochromat Lambda S correction delivers the highest level of chromatic aberration correction for sharp, high-contrast multi-color fluorescence images across the full visible spectrum. The adjustable working distance and coverslip correction collar (0.11–0.23mm) accommodate a wide range of vessel types and coverslip thicknesses, enhancing throughput in cell screening and live imaging applications. New, open box condition.
