Meiji MA622 4x Plan Achromat Objective

N.A.0.10，F.L.39.09mm,W.D.9.6mm

这种Meiji Techno生物Brightfield物镜 - 通过直立校正的非感染性 - 生物学显微镜以最高的日本质量和光学标准制作，利用非侵入性管镜头设计F = 160mm。旨在满足最先进的生物成像要求。这个目标代表了明治技术的光学技术的高潮。这一目标提高了亮度，并且在同类课程中提高了最高的N.A.，以获得最大的收集能力。旨在校正整个视野中的横向和轴向色差。该目标产生平坦，清晰且清晰的图像，具有高对比度和光学分辨率。该目标可与广泛的应用程序一起使用。所述的放大倍数基于160 mm的管镜头。DIN标准安装线为0.7965英寸（20.1mm）直径螺纹，36 TPI（每英寸线），55°Whitworth。此目标与所有非智力校正的光学系统兼容。

在设计目标是至关重要的Meiji Techno Japanese Engineers to set the ultimate resolution limit of the optical microscope. The important factors is to include the wavelength of light used to illuminate the specimen sample, the angular aperture of the light cone being captured by the objective and as important is the refractive index in the object distance between the objective front lens and the specimen. Resolution can be measured as the minimum detectable distance between two closely spaced specimen points of interest.
