Zeiss Objective Achroplan 100x PH2 Objective

The Zeiss Achroplan 100x/1.25 Ph2 objective is a high-performance oil immersion lens engineered for demanding biological microscopy applications requiring maximum resolution and contrast. With a numerical aperture of 1.25, this objective delivers the resolving power necessary to visualize subcellular structures, bacterial morphology, and fine tissue details that remain invisible at lower magnifications.

The integrated Ph2 phase contrast ring transforms this objective into a powerful tool for live cell imaging, enabling researchers to observe cellular dynamics, organelle movement, and morphological changes in real time without the need for staining or fixation. The achroplan optical design provides excellent color correction and flat-field imaging across the entire field of view, ensuring accurate documentation and analysis.

As an infinity-corrected objective, this lens is designed for modern Zeiss microscope systems and is fully compatible with intermediate optical components such as DIC prisms, fluorescence filter cubes, and camera adapters without introducing optical aberrations. The RMS threading ensures broad compatibility across Zeiss platforms. With a working distance of 0.19mm, this objective requires proper immersion oil technique and thin coverglass (0.17mm) for optimal performance. Catalog number 440081.
