N.A. 0.90, F.L. 2.0mm, W.D. 0.37mm
The Meiji Techno MA874 Plan Achromat Epi 100× objective delivers crisp, high-contrast metallurgical images using an infinity-corrected optical design (F = 200 mm). Its large numerical aperture maximizes light gathering and, together with full-field correction of lateral and axial chromatic aberrations, ensures flat, uniformly sharp images. Machined to DIN standard (0.7965" Ø, 36 TPI Whitworth, 55°) and compatible with all infinity-corrected systems, it fits both upright and inverted microscopes for versatile industrial and research applications.
The MA874 Plan Achromat Epi 100x metallurgical objective lens is also factory-integrated in Meiji Techno’s MC-40, MC-45, MC-50, MC-55, MCS-40, MCS-50, MT7000, MT8000, and IM7000 series.
