Nikon CFI Apo NIR 60x Water Immersion Objective

The Nikon CFI Apo NIR 60X is a specialized water dipping objective engineered specifically for multiphoton microscopy and deep tissue imaging applications. As part of Nikon's Apo NIR series, this objective delivers apochromatic correction optimized for near-infrared wavelengths, making it ideal for multiphoton excitation and NIR fluorescence imaging. Unlike conventional water immersion objectives requiring coverslips, this dipping objective is designed for direct immersion into aqueous solutions, making it perfect for imaging brain slices, organotypic cultures, and other live tissue preparations in physiological buffers. With a numerical aperture of 1.00 and 60X magnification, this objective provides excellent resolution for detailed cellular imaging, while the long 2.8mm working distance provides exceptional clearance for micromanipulation equipment and deep tissue penetration. The water immersion design eliminates refractive index mismatches, ensuring optimal image quality when imaging deep into aqueous preparations. Compatible with Nikon's CFI infinity optical system, this objective integrates seamlessly with Eclipse FN1 and other upright research microscopes, making it essential for laboratories conducting multiphoton imaging, neuroscience research, deep tissue imaging, and live cell observation. This objective is in factory-new condition.
