Olympus UPLANXAPO 100X Phase Contrast Objective

The Olympus UPLANXAPO 100X PH3 phase contrast objective is specifically engineered for ultimate resolution phase contrast microscopy with superior optical performance. The UPLANXAPO (Universal Plan Apochromat) optical design represents the highest level of optical correction, combining plan (flat-field) correction with apochromatic color correction across a wide wavelength range, delivering exceptional image flatness and 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 PH3 designation indicates this objective is optimized for use with 100x phase contrast condensers. At 1.45 numerical aperture with oil immersion, this objective provides maximum resolution at the theoretical limits of light microscopy. 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 (special order item) ensures optimal optical performance and reliable operation for the most demanding research and imaging applications.
