Olympus UPLANFL N 40x Phase Contrast Objective

The Olympus UPLANFL N 40X PH2 phase contrast objective is specifically engineered for high-resolution phase contrast microscopy with superior optical performance using oil immersion. The plan fluorite (UPLANFL) optical design combines plan (flat-field) correction with fluorite elements, delivering exceptional image flatness across the entire field of view with superior chromatic aberration correction. 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 0.75 numerical aperture with oil immersion, this objective provides exceptional resolution for detailed cellular imaging at high magnification. Oil immersion eliminates light loss at the glass-air interface, enabling maximum light-gathering capability and resolution. 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.
