Olympus Plan N 40x Phase Contrast Objective

The Olympus PLAN N 40X PH2 phase contrast objective is specifically engineered for high-resolution phase contrast microscopy with plan achromat optical design. The plan achromat design provides flat-field correction across the field of view, ensuring sharp focus from center to edge. Phase contrast microscopy enhances contrast in transparent, unstained specimens by converting phase shifts in light passing through the specimen into amplitude changes, making cellular structures visible without staining. The PH2 designation indicates this objective is optimized for use with 40x phase contrast condensers. At 0.60 numerical aperture with 0.65mm working distance, this objective provides excellent resolution for detailed cellular imaging at high magnification. The RMS thread ensures compatibility with Olympus infinity corrected microscope systems. Factory-new condition ensures optimal optical performance and reliable operation for demanding research, clinical, and laboratory applications.
