Zeiss Plan-Apochromat 63x/1.4 Oil Immersion Objective (NA 1.40, Infinity, RMS)

The Zeiss Plan-Apochromat 63×/1.4 Oil RMS is the legacy RMS thread version of Zeiss’s benchmark 63× plan apochromat objective — optically identical in performance to the current M27 version but with the older RMS thread mount used on Zeiss Axioskop, Axiovert, and Axioplan series microscopes. For labs running these older Zeiss platforms, this objective provides the full plan apochromat optical performance — NA 1.40 oil immersion, flat-field correction, and apochromat chromatic registration across all fluorescence channels — at a significant discount to the current M27 version. At NA 1.40, this objective delivers the maximum resolution and fluorescence light collection available in oil immersion, making it the definitive choice for high-resolution confocal, TIRF, single-molecule, and super-resolution imaging on compatible Zeiss systems. 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. This unit is offered in excellent condition with flawless optics at a significant discount to the list price of $5,600. Catalog number 1113-106.
