Zeiss W Plan-Apochromat 20x Water Dipping Objective UV VIS-IR

The Zeiss W Plan-Apochromat 20x Water Dipping objective represents the pinnacle of water immersion optics, combining the superior color correction of plan apochromat design with the exceptional numerical aperture of 1.0 in water for unparalleled resolution in live-tissue imaging. This objective delivers chromatic correction across three wavelengths and spherical aberration correction at two wavelengths, ensuring color-accurate, high-contrast images with minimal optical artifacts across the entire UV-visible-infrared spectrum. The 1.0 numerical aperture in water approaches the theoretical maximum for water immersion, enabling resolution comparable to oil immersion objectives while maintaining the physiological compatibility essential for living specimens. At 20x magnification, this objective provides an ideal balance between resolution and field of view for deep-tissue imaging, brain slice electrophysiology, and advanced multiphoton microscopy. The 1.8mm working distance enables imaging deep into tissue while accommodating micromanipulators and recording electrodes. The M27 thread mount ensures compatibility with Zeiss Axio and other infinity-corrected platforms. This objective is the ultimate tool for demanding neuroscience applications including two-photon calcium imaging, deep-tissue multiphoton microscopy, and any application requiring maximum resolution and optical performance in living aqueous preparations.
