Zeiss EC Plan-Neofluar 40x/1.30 Oil Immersion Objective (NA 1.30, Infinity, M27)

The Zeiss EC Plan-Neofluar 40×/1.30 Oil is a versatile high-performance objective from Zeiss’s EC (Enhanced Contrast) series — a line specifically engineered to minimize stray light and maximize contrast across all imaging modalities. The EC designation indicates that this objective has been optimized to reduce internal reflections and stray light compared to standard Plan-Neofluar objectives, resulting in visibly improved contrast in brightfield, darkfield, phase contrast, DIC, fluorescence, and polarization imaging. This makes the EC Plan-Neofluar series particularly valuable for labs that use multiple contrast techniques on the same specimens, as a single objective delivers optimized performance across all modalities without compromise. At NA 1.30 with oil immersion, this objective provides excellent resolution and fluorescence light collection at 40× — a magnification that offers a good balance between field of view and resolution for cell biology, histology, and materials imaging. The Plan-Neofluar fluorite elements provide excellent chromatic correction and UV-visible transmission for multi-channel fluorescence imaging. This unit is offered in lightly used condition with perfect optics at a significant discount to the new list price of $6,200. Compatible with Zeiss Axiovert, Axioplan, Axio Observer, Axio Imager, and Axio Examiner microscopes with M27 thread nosepieces. Catalog number 420460.
