Olympus Plan N 10X Microscope Objective (PLN10X, NA 0.25, Infinity)

The Olympus PLN 10× Objective is a versatile microscope objective engineered for general-purpose imaging across a wide range of microscopy applications. With 10× magnification and a numerical aperture (NA) of 0.30, this objective strikes an optimal balance between image resolution, brightness, and depth of field — making it a reliable choice for brightfield, darkfield, phase contrast, and many fluorescence modalities.

Its Plan optical design ensures flat field correction and minimizes chromatic and spherical aberrations, resulting in uniformly sharp and high-contrast images across the entire field of view. This makes it ideal for routine observation, documentation, and quantitative analysis in research, clinical, and educational laboratories.

The working distance of approximately 10 mm provides ample room between the objective and the sample, allowing room for slide manipulation, micro-tools, perfusion chambers, or accessory devices without compromising optical performance. Combined with its standard RMS threaded mount, this objective is compatible with a broad range of upright microscope systems used in life science and material science workflows.
