Zeiss Plan-Apochromat 63x/1.4 Oil Immersion Objective (NA 1.40, Infinity, M27)

The Zeiss Plan-Apochromat 63×/1.4 Oil is one of the most widely used high-performance objectives in biological research — a benchmark objective for confocal, live-cell, and super-resolution microscopy. At 63× with NA 1.40, this objective provides the ideal combination of high magnification and maximum oil immersion NA for single-cell and subcellular imaging, delivering the resolution and fluorescence light collection required for the most demanding imaging applications. 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. The 63× magnification is the preferred choice for many researchers on Zeiss systems, providing a slightly larger field of view at equivalent NA compared to 60× objectives. This unit is offered in lightly used condition with flawless optics — optically indistinguishable from new — at a significant discount to the new list price of $6,500. Note: this is the standard version without DIC capability (catalog 420780); the DIC version is catalog 420782. Compatible with Zeiss Axiovert, Axioplan, Axio Observer, Axio Imager, and Axio Examiner microscopes with M27 thread nosepieces. Catalog number 420780-9900.
