Zeiss LD Plan-Neofluar 63x/0.75 Long Working Distance Objective (NA 0.75, Infinity, M27)

The Zeiss LD Plan-Neofluar 63×/0.75 M27 is a long working distance objective engineered for cell biology workflows where specimens are imaged through thick plastic substrates — multi-well plates, Petri dishes, T-flasks, and imaging chambers — that standard short-working-distance objectives cannot accommodate. The 2.2mm working distance provides ample clearance for the full range of standard tissue culture vessels, enabling high-magnification fluorescence and brightfield imaging of living cells in standard culture conditions without the need to transfer cells to specialized coverslip-bottom dishes. This is the standard (non-phase-contrast) version of the LD Plan-Neofluar 63× — catalog number 421380 — suitable for fluorescence, DIC, and brightfield imaging workflows that do not require phase contrast. The Plan-Neofluar fluorite design provides excellent chromatic correction and high fluorescence transmission for multi-channel imaging across the visible spectrum. The M27 thread mount is the current Zeiss standard, compatible with Zeiss Axiovert, Axio Observer, Axio Imager, and Axio Examiner microscopes. This unit is offered in excellent condition with flawless optics at a significant discount to the new list price of $6,750. Catalog number 421380.
