Nikon CFI Plan Apo IR 60x Water Immersion Objective

The Nikon CFI Plan Apo IR 60X represents the pinnacle of water immersion objective design, providing the world's highest numerical aperture of 1.27 for water immersion objectives. As part of Nikon's Plan Apo IR series, this objective delivers exceptional apochromatic correction extending to 1,604 nm, making it ideal for near-infrared (NIR) imaging, multiphoton microscopy, and advanced fluorescence applications. With an ultra-high numerical aperture of 1.27, this objective provides outstanding resolution and light-gathering efficiency for demanding imaging techniques. The water immersion design provides refractive index matching for deep tissue imaging, reducing spherical aberration when imaging into thick specimens. The extended chromatic correction to 1,604 nm makes this objective essential for multiphoton excitation, NIR fluorescence, laser trapping, and other advanced techniques requiring infrared wavelengths. The working distance of 0.18–0.16mm with correction collar allows precise optimization for various specimen preparations. Compatible with Nikon's CFI infinity optical system, this objective integrates seamlessly with Eclipse Ti2, Ni-E, and A1 series research microscopes, making it essential for laboratories conducting cutting-edge NIR imaging, multiphoton microscopy, confocal microscopy, DIC imaging, and laser trapping applications. This is a demonstration model in excellent working condition.
