摘　　要：设计了波段300nm～500nm,放大倍率为10×,NA=0.3的近紫外-可见光显微物镜,用于观测激光照射核聚变的成像过程。该系统采用透射式结构,通过P、W设计方法和CODE-V软件的优化,实现了系统的复消色差,较好地解决了紫外光学材料种类少、折射率低带来的像差校正困难和光学系统效率不高的问题。A customized microscope objective for near ultraviolet（UV）-visible spectrum was designed,which was used to observe the image of nuclear fusion irradiated by laser.The operation wavelength was 300 nm～500 nm,the magnification was 10× and the numerical aperture（NA） was 0.3.The transmission-mode structure was established in the microscope objective,by theoretical calculation with PW method and optimization with CODE-V,the apochromatism was achieved.Thus,the problems such as difficult aberration correction and low efficiency of optical system,resulted from the few kinds of UV optical materials and low refractive index,could be solved.
