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.
