摘要
对自聚焦透镜的光斑尺寸和像差特性进行了理论分析.利用自聚焦透镜光斑测量系统对样品的出射光斑进行了扫描,测得了光斑的大小;用读数显微镜和正方形网格图分别测量了样品的球差和畸变,并对光斑的测量作了误差分析,讨论了球差与畸变、光斑和像差之间的关系.所得结果对光斑质量的改善、像差特性的研究和自聚焦透镜的评估有一定的参考价值.
The optical spot and aberration properties of selfoc lenses were analyzed.Optical spot was scanned by optical spot measurement system,so the spot′s size was obtained.The aberration was measured by reading microscope and foursquare grid chart.And then the error of the measurement of optical spot was analysed.The relation between aberration and spot size was discussed.The results are certain reference value on improvement of spot′s quality,research of aberration property and evaluation of quality of selfoc lens.
