Leica HCX PL APO 63x/1.30 Glycerol Immersion Objective (NA 1.30, Infinity)

The Leica HCX PL APO 63×/1.30 Glycerol is a specialized objective engineered for the demands of live-cell and deep tissue fluorescence microscopy where refractive index matching to the specimen is critical. Glycerol immersion (n≈1.45) sits between water (n=1.33) and oil (n=1.515) and closely matches the refractive index of living cells and biological tissues (~1.38–1.46), dramatically reducing spherical aberration when imaging deep into living specimens — maintaining image quality and resolution at depths where water immersion objectives suffer increasing aberration and oil immersion is incompatible with aqueous specimens. The HCX PL APO correction delivers Leica’s highest level of chromatic and spherical aberration correction, ensuring accurate co-localization across all fluorescence channels. At 63× with NA 1.30, 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 — optically indistinguishable from new — at a significant discount to the new list price of $7,500. Compatible with Leica DMI, DM, and SP series confocal microscopes with M25 thread nosepieces. Catalog number 506193.
