Olympus MPLAPON 100x/1.40 Oil Immersion Reflected Light Objective (NA 1.40, Infinity)

The Olympus MPLAPON 100×/1.40 Oil is the highest-performance objective in the Olympus MPLAPON reflected light series — delivering NA 1.40 oil immersion with plan apochromat correction for the most demanding industrial and materials science microscopy applications. At NA 1.40, this objective provides the maximum resolution available in reflected light oil immersion microscopy, enabling visualization of the finest microstructural details in metals, alloys, semiconductors, ceramics, and other opaque materials. The plan apochromat correction ensures flat-field imaging with accurate chromatic registration across the full field of view, essential for quantitative metallographic analysis, semiconductor defect inspection, and documentation where image accuracy is critical. Oil immersion at 100× provides significantly higher resolution than dry objectives at equivalent magnification, making this objective the definitive choice when maximum resolving power is required for fine grain structure, thin film analysis, or sub-micron feature inspection. Compatible with Olympus BX, MX, and GX series industrial and materials microscopes with RMS thread nosepieces. This unit is offered in excellent condition with flawless optics at a significant discount to the new list price of $5,900. SKU MPLAPON100XO.
