Nikon CFI Plan Fluor 40x/1.30 Oil Immersion Objective (NA 1.30, Infinity, M25)

The Nikon CFI Plan Fluor 40×/1.30 Oil is one of the most widely used high-performance objectives in biological research — a versatile workhorse objective combining NA 1.30 oil immersion with Plan Fluor fluorite correction for excellent performance across fluorescence, brightfield, DIC, and phase contrast imaging. The Plan Fluor fluorite design delivers superior UV-visible transmission compared to standard achromat objectives, making it suitable for UV-excited fluorophores (DAPI, Hoechst, fura-2) alongside standard visible fluorophores in multi-channel imaging workflows. At NA 1.30 with oil immersion, this objective provides excellent resolution and fluorescence light collection for single-cell and subcellular imaging — protein localization, organelle dynamics, and multi-channel co-localization studies. The 40× magnification provides a practical balance between field of view and resolution for a wide range of biological imaging applications. This unit is offered in excellent condition with flawless optics at a significant discount to the new list price of $5,995. Compatible with Nikon CFI series microscopes including Eclipse Ti2, Ti, Ni, E, and FN series. Catalog number MRH01400.
