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. Compatible with Nikon CFI Ti2, Eclipse Ni, Ni-U, and related CFI system microscopes.
