Nikon CFI Plan Apo 20x Lambda Objective

The Nikon CFI Plan Apo Lambda 20x objective represents the pinnacle of Nikon's optical engineering, combining plan apochromat correction with revolutionary Nano Crystal Coat technology for ultimate imaging performance. The "Lambda" designation indicates Nikon's most advanced objective series, featuring ultra-low refractive index Nano Crystal Coat that virtually eliminates internal reflections and ghost images across the entire visible spectrum. This advanced coating technology, originally developed for Nikon's professional camera lenses, delivers exceptional contrast and color fidelity by minimizing light loss and optical artifacts. The plan apochromat optical design provides chromatic correction across four wavelengths and spherical aberration correction at multiple wavelengths, ensuring color-accurate, high-contrast images with minimal optical aberrations. At 20x magnification with 0.75 numerical aperture, this objective delivers excellent resolution and light-gathering capability for detailed cellular imaging and high-resolution visualization of biological specimens. The 1.0mm working distance accommodates standard microscope slides with #1.5 coverslips. The CFI (Chrome-Free Infinity) optical system eliminates environmentally harmful chromium from lens coatings while maintaining superior optical performance. The M25 thread mount ensures compatibility with all Nikon infinity-corrected microscope platforms. This objective is the ultimate tool for advanced fluorescence microscopy, confocal imaging, live-cell studies, and any application demanding the highest optical performance and color fidelity.
