Olympus PLN 20X, Ph1, Phase Contrast Objective

Product Details Flat-Field Plan Achromat Design for Sharp, Distortion-Free Images Precision Phase Ring Matching (Ph1, Ph2, Ph3) For Optimal Contrast Available In Multiple Magnifications (10X, 20X, 40X) Plus A 100X Oil Immersion Option Optimized For the UIS2 Optical System, Ensuring Seamless Integration with Olympus CX43 Olympus PLN Phase Contrast Objectives provide high-performance imaging for precise cellular analysis on the Olympus CX43 microscope. These objectives are engineered for accurate phase contrast imaging across magnifications, offering excellent contrast and flat-field correction. Designed specifically for the UIS2 optical system, they deliver sharp, high-clarity images ideal for live, unstained specimens. Olympus PLN Phase Contrast Objectives, such as the 10X Ph1 ( #86-935 ) and 100X Ph3 oil ( #87-013 ), ensure reliable results across a wide range of biological applications. Their consistent quality and compatibility with standard Olympus phase contrast condensers make them a trusted choice for professional labs.
