摘要 为解决普通生物显微物镜视场小、场曲和色差严重的问题,本文利用光学软件Code V设计了一款20×平场复消色差显微物镜,通过合理的结构优化、光焦度分配及材料选择,使该物镜具有大视场、高数值孔径、平场复消色差的特点。设计分析结果表明,该物镜平场数为0.11μm,最大焦移量为0.5μm,满足显微物镜国际标准的规定;光学传递函数(MTF)曲线与理论衍射极限接近,达到指标要求,该物镜在可见光范围内实现了平场复消色差设计。公差分析结果表明RMS波前差劣化至0.24λ,能够满足加工和实际应用要求。 To improve the common microscope objective with small field of view,poor field curve and chro-matic aberration correction,A 20 ×plan-apochromatic microscope objective is designed in this paper by Code V software.This objective has a large field of view,high N.A.,and plan-apochromatic characteristic de-signed by reasonable structure optimization,focal power distribution and material selection.The result shows that the objective is a plan-apochromatic lens in visible wide band.The plan field number is 0.1 1 μm and the largest focal shift is 0.5 μm,which meet the specification of the international standard for microscope objec-tives.The MTF curve is closed to the diffraction limit.The tolerance analysis shows that RMS wavefront error gets worse to 0.24λand the objective lens can be applied and manufactured actually.
