【摘要】 高倍率显微物镜一般工作距离只有零点几毫米,由于这一局限性,很多需要用到高倍率显微物镜的测试的场合都无法顺利完成。所以在一定的测试场合,例如CCD几何量测试时高倍率显微物镜工作距离的加长显得非常关键。文中分别从用途和数值孔径两种角度对显微镜进行了分类,结合两种分类的特点。选择了用于CCD几何量测试的高倍率显微物镜的初始结构,对其进行了复杂化,最终设计了一个β=40x、NA=0.7、工作距离为5mm的显微物镜。并分别从几何像差、传递函数、点列图、能量曲线评价了这一物镜的成像质量。更多还原

【Abstract】 High-magnification microscope objectives work in general is only 0:00 away from a few millimeters,due to this limitation,many high-magnification microscope objectives need to use the occasion of the tests can not be successfully completed.So in a certain test occasions,such as the amount of testing geometry CCD high-rate of the longer working distance microscope objectives are vital.Paper,respectively,from the perspective of two kinds of uses and a numerical aperture of the microscope,have been classified,combined with the characteristics of both classifications.Selected geometrical parameters for the CCD tested high-magnification microscope objectives of the initial structure and to carry out a more complicated,the final design of a,NA = 0.7,working distance of 5 mm of the microscope objectives.Respectively,from the geometrical aberrations,transfer function,point out diagram,the energy curve to evaluate the image quality of this lens.更多还原
