M Plan Apo HR Series Objectives

Dry lens "peak performance": NA=0.75 + 50x magnification, 0.4μm resolution approaching the 550nm wavelength diffraction limit (theoretical ~0.41μm); 5.2mm working distance breakthrough: still retaining an operating space of more than 5mm under high NA, suitable for ultra-thin sections (≤5μm) or chip observation.

Applications:

• Nanoparticle size/distribution analysis (gold nanoparticles, quantum dots)
• Observation of protein crystal lattice contours
• Ultra-fine structures of metal twin boundaries (such as stainless steel martensite)
