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

The Zeiss Plan-Apochromat 100×/1.4 Oil DIC Objective (RMS) is the legacy RMS thread version of Zeiss’s flagship 100× plan apochromat — delivering NA 1.40 oil immersion with full plan apochromat correction and DIC (Nomarski) capability for older Zeiss microscopes with RMS nosepieces including Axioskop, Axiovert, and Axioplan series. Offered here new/open box at significant savings versus the list price.

• 🔬 NA 1.40 oil immersion — maximum available — the highest numerical aperture achievable in oil immersion, delivering the ultimate resolution and fluorescence light collection for TIRF, single-molecule, super-resolution, and confocal imaging at 100×
• 🌟 Plan apochromat correction — Zeiss’s highest level of chromatic and spherical aberration correction for accurate multi-channel fluorescence co-localization and brilliant flat-field imaging across the full visible spectrum
• 🔍 DIC (Nomarski) compatible — optimized for differential interference contrast imaging of living cells and unstained specimens alongside fluorescence and brightfield at 100×
• 🔧 RMS thread mount — legacy Zeiss RMS format, compatible with older Zeiss Axioskop, Axiovert, and Axioplan series microscopes with RMS nosepieces; not compatible with current M27 nosepieces without an adapter
• 🇩🇪 Zeiss quality, made in Germany — precision optical construction for consistent, high-efficiency light transmission and long service life
• ✅ Condition: New / open box — catalog number 440782

🔧 Product Description

The Zeiss Plan-Apochromat 100×/1.4 Oil DIC RMS is the legacy RMS thread version of Zeiss’s definitive 100× biological objective — combining NA 1.40 oil immersion, plan apochromat correction, and DIC capability in the older RMS thread format for Zeiss Axioskop, Axiovert, and Axioplan microscopes. For labs running these legacy Zeiss platforms, this objective delivers the full plan apochromat optical performance — NA 1.40 oil immersion, flat-field correction, and apochromat chromatic registration across all fluorescence channels — in new/open box condition at a significant discount to the current list price. 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 DIC compatibility enables high-contrast transmitted light imaging of living cells and unstained specimens alongside fluorescence — a critical capability for correlating cell morphology with fluorescence signals in live-cell imaging workflows. 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. Supplied new/open box at a significant discount to the list price of $5,800. Catalog number 440782.
