• 📐 M27 thread mount — compatible with Zeiss Axio series microscopes including Axiovert, Axioplan, Axio Observer, Axio Imager, and Axio Examiner
• 🇩🇪 Zeiss quality, made in Germany — precision optical construction for consistent, high-efficiency light transmission and long service life
• ✅ Condition: Flawless, as new — catalog number 420762

🔧 Product Description

The Zeiss Plan-Apochromat 40×/1.4 Oil DIC is one of the most widely used high-performance objectives in biological research — combining NA 1.40 oil immersion with full plan apochromat correction across the UV, visible, and near-infrared spectrum. The (UV) VIS-IR designation indicates that this objective maintains apochromat-level chromatic correction from the UV (below 400nm) through the near-infrared (beyond 700nm), making it suitable for the widest range of fluorophores and imaging modalities including UV-excited dyes, visible fluorophores, and NIR probes in a single objective without chromatic compromise. 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. The DIC compatibility enables high-contrast transmitted light imaging of unstained specimens alongside fluorescence. This unit is offered in flawless, as-new condition — optically and mechanically indistinguishable from new — at a significant discount to the current new list price of $14,900. Compatible with Zeiss Axiovert, Axioplan, Axio Observer, Axio Imager, and Axio Examiner microscopes with M27 thread nosepieces. Catalog number 420762.

🔎 Typical Applications
