🔧 Product Description

The Zeiss LD Plan Neofluar 40X Ph2 (421361) is a long working distance objective combining the renowned fluorescence performance of the EC Plan Neofluar series with a correction collar adjustable from 0 to 1.5 mm — allowing precise compensation for varying coverslip thicknesses and culture vessel bottom variations. With a 2.9 mm working distance and 0.60 NA, it delivers high-resolution phase contrast imaging of live, unstained cells through the walls of culture flasks, multi-well plates, and Petri dishes. Beyond phase contrast (PH2), it performs equally well in brightfield, DIC, PlasDIC, and fluorescence — making it one of the most versatile objectives in the Zeiss portfolio. M27 thread, infinity corrected. Excellent condition with flawless optics. Manufactured in Germany to Zeiss's exacting standards.
