🔧 Product Description

The Zeiss EC Plan-Neofluar 63×/0.95 Corr is a premium dry objective combining the highest NA available in a dry 63× format with Zeiss Plan-Neofluar fluorite correction and a correction collar for coverslip thickness compensation. The EC (Extra Chromatic) designation indicates enhanced chromatic correction compared to standard Plan-Neofluar objectives, providing improved color accuracy for multi-channel fluorescence imaging. The correction collar allows fine adjustment for different coverslip thicknesses, ensuring optimal spherical aberration correction and maintaining image quality across different specimen preparations — a significant advantage over fixed-correction dry objectives. At NA 0.95, this objective provides resolution approaching that of lower-NA immersion objectives without the need for immersion media — making it ideal for high-throughput screening, slide scanning, and workflows where the convenience of a dry objective is preferred at 63× magnification. The Plan-Neofluar fluorite elements provide excellent UV-visible transmission for fluorescence imaging alongside high-contrast brightfield and DIC performance. This unit is offered in excellent condition with flawless optics at a significant discount to the new list price of $7,600. Compatible with Zeiss Axiovert, Axioplan, Axio Observer, Axio Imager, and Axio Examiner microscopes with M27 thread nosepieces. Catalog number 420380.
