The Mitutoyo BD Plan Apo series is engineered for both brightfield and darkfield reflected light microscopy, offering exceptional apochromatic correction and ultra-flat field imaging from 2x to 100x magnification. These objectives are ideal for applications that require enhanced edge contrast and surface detail—such as semiconductor inspection, MEMS analysis, and materials science.
With long working distances, no cover glass requirement, and built-in BD illumination support, these objectives provide unmatched flexibility and clarity across both lighting modes. Whether you’re visualizing micro-scratches, profiling polished surfaces, or inspecting layered structures, the BD Plan Apo line ensures consistent, high-resolution results.
