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. This unit is offered in excellent condition with flawless optics at a significant discount to the new list price of $7,800.
