Zeiss Plan-Neofluar 63x/0.95 KORR Dry Objective with Correction Collar (NA 0.95, Infinity, RMS)

The Zeiss Plan-Neofluar 63×/0.95 KORR RMS 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 — in the legacy RMS thread format for older Zeiss microscope platforms. The correction collar (KORR) allows fine adjustment for different coverslip thicknesses, ensuring optimal spherical aberration correction regardless of the coverslip used — a significant advantage over fixed-correction dry objectives, particularly valuable in labs that use different coverslip types across different specimen preparations. At NA 0.95, this objective provides resolution approaching that of lower-NA immersion objectives without the need for immersion media — ideal for high-throughput screening, slide scanning, and workflows where the convenience of a dry objective is preferred at 63×. The Plan-Neofluar fluorite elements provide excellent UV-visible transmission for fluorescence imaging alongside high-contrast brightfield and DIC performance. For labs running legacy Zeiss Axioskop, Axiovert, or Axioplan microscopes with RMS nosepieces, this objective delivers full Plan-Neofluar KORR performance at a significant discount. This unit is offered in excellent condition with flawless optics at a significant discount to the list price of $5,800. Catalog number 440364.
