Nikon CFI LWD 16X Water Dipping Microscope Objective

The Nikon CFI LWD 16X Water Dipping Objective is a specialized high-performance objective engineered specifically for electrophysiology, neuroscience research, and live tissue imaging applications. Unlike conventional water immersion objectives that require a coverglass, this dipping objective is designed for direct immersion into aqueous solutions, making it ideal for imaging brain slices, organotypic cultures, and other live tissue preparations in physiological buffers. The high numerical aperture of 0.80 provides exceptional resolution and light-gathering capability, enabling visualization of fine cellular structures and subcellular details in living tissue. The long 3mm working distance allows deep penetration into thick tissue slices while providing ample clearance for micromanipulation equipment such as patch-clamp electrodes, microinjection needles, and stimulation probes. The water immersion design eliminates refractive index mismatches between the objective and specimen, ensuring optimal image quality and contrast when imaging deep into aqueous preparations. Compatible with Nikon's CFI60 infinity optical system, this objective integrates seamlessly with Eclipse FN1 and other upright research microscopes equipped for electrophysiology, making it an essential tool for laboratories conducting patch-clamp recordings, calcium imaging, optogenetics, and other advanced neuroscience techniques requiring simultaneous high-resolution imaging and physiological manipulation.
