Olympus Plan N 20x Phase Contrast Objective

The Olympus PLAN N 20X PH1 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 PH1 designation indicates this objective is optimized for use with 20x phase contrast condensers. At 0.40 numerical aperture with 1.2mm working distance, this objective provides excellent resolution for detailed cellular imaging. 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.
