Zeiss Plan-Apochromat 100x/1.4 Oil Immersion Objective (NA 1.40, Infinity, M27)

The Zeiss Plan-Apochromat 100×/1.4 Oil is the definitive high-magnification objective for biological research on Zeiss microscopes — combining NA 1.40 oil immersion with full plan apochromat correction for the highest resolution and optical performance available at 100×. At NA 1.40, this objective delivers the maximum resolution and fluorescence light collection available in oil immersion, making it the standard choice for high-resolution confocal, TIRF, single-molecule, and super-resolution imaging where every photon counts. The plan apochromat correction ensures accurate chromatic registration across all fluorescence channels, essential for multi-color co-localization, FRET, and any imaging workflow where chromatic shift between channels would compromise data integrity. At 100×, this objective provides the magnification needed for subcellular imaging, organelle dynamics, protein localization, and single-molecule studies. This unit is offered in excellent condition with flawless optics — optically and mechanically indistinguishable from new — at a significant discount to the new list price of $8,600. Compatible with Zeiss Axiovert, Axioplan, Axio Observer, Axio Imager, and Axio Examiner microscopes with M27 thread nosepieces. Catalog number 420790.
