Nikon CFI Plan Apo 10x Lambda Objective

The Nikon CFI Plan Apo Lambda 10x objective represents the pinnacle of Nikon's optical engineering at mid-magnification, combining plan apochromat correction with revolutionary Nano Crystal Coat technology and exceptional working distance. 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 from UV to IR. 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 10x magnification with 0.45 numerical aperture, this objective delivers excellent resolution and light-gathering capability while maintaining an exceptional 4.0mm working distance—significantly greater than standard 10x objectives. This extended working distance provides valuable clearance for thick specimens, culture vessels, or experimental access. 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 specimen overview, navigation, and applications demanding the highest optical performance at mid-magnification with extended working distance.
