Water immersion (n=1.33) eliminates the refractive index mismatch between the objective and aqueous biological specimens, reducing spherical aberration and maintaining image quality when imaging into living cells and tissues. The correction collar (0.14–0.18mm) allows fine adjustment for different coverslip thicknesses, ensuring optimal spherical aberration correction regardless of the coverslip used — a significant advantage over fixed-correction water immersion objectives, particularly in labs that use different coverslip types or image through varying thicknesses of media. The plan apochromat correction delivers Leica’s highest level of chromatic and spherical aberration correction, ensuring accurate co-localization across all fluorescence channels. At 63× with NA 1.20, this objective provides high-resolution single-cell and subcellular imaging with excellent fluorescence light collection.

The APO (apochromat) correction delivers the most accurate chromatic aberration correction available, ensuring that fluorescence signals from multiple channels are precisely co-registered — critical for co-localization studies, FRET experiments, and any multi-color imaging workflow where chromatic shift between channels would compromise data integrity. The Lambda S designation indicates optimization for reduced focus shift across wavelengths, making this objective particularly well-suited for multi-color confocal, structured illumination (SIM), and TIRF microscopy where maintaining parfocality across channels is essential. The long working distance (LWD) of 0.61mm provides more clearance than standard 40× water immersion objectives, accommodating thicker coverslips, imaging chambers, and experimental setups where additional working room is needed. Water immersion (n=1.33) eliminates the refractive index mismatch between the objective and aqueous biological specimens, reducing spherical aberration and maintaining image quality when imaging into living cells and tissues.

The W LSM designation indicates that this objective has been engineered for laser scanning microscopy applications, with optical coatings and glass elements selected for high transmission across the broad spectral range required for two-photon excitation (typically 700–1000nm NIR) as well as the visible spectrum for confocal imaging. Water immersion is the preferred medium for deep tissue imaging because its refractive index (n=1.333) closely matches that of biological cytoplasm (~1.38) and aqueous specimens, minimizing spherical aberration as the focal plane moves deeper into tissue — a critical advantage over oil immersion objectives, which introduce increasing spherical aberration with depth due to refractive index mismatch. The 1.0mm working distance provides practical depth access for imaging thick brain slices, tissue sections, organoids, and other thick biological specimens. The plan apochromat correction ensures accurate chromatic registration across all fluorescence channels for multi-color deep tissue imaging. Compatible with Olympus BX, CX, and IX series microscopes with RMS nosepieces. This unit is offered in excellent condition with flawless optics at a significant discount to the list price of $5,600.
