🔧 Product Description

The Nikon CFI Plan Apo LWD Lambda S 40XC WI (MRD77415) is a premium water immersion objective from Nikon's Lambda S series, engineered for the most demanding confocal, multiphoton, and super-resolution imaging applications. With a 1.15 NA and plan apochromat correction, it delivers the highest class of optical performance — flat field, minimal chromatic aberration, and maximum resolution — across a broad wavelength range including near-infrared. The “Lambda S” designation indicates enhanced correction for longer wavelengths, making it particularly well-suited for multiphoton excitation and NIR fluorescence imaging. The correction collar (0.15–0.19mm) allows precise compensation for coverslip thickness variation, ensuring optimal image quality across different sample preparations. The 0.63mm working distance provides comfortable clearance for water immersion at 40X. Compatible with all Nikon CFI infinity corrected microscopes. Manufactured in Japan to Nikon’s exacting standards.

🔎 Typical Applications
