摘要
在HL_2A托卡马克装置上,利用电荷交换复合光谱方法测量高温等离子体的粒子参数是十分有效的。为了获得在可见光谱段480~650 nm的信号,满足在斜视的空间几何位置上获得较大的观察视场,以及要满足光纤数值孔径很小等要求,利用ZEMAX光学设计软件设计了一组由一个反射镜,4片透镜组成的光学系统,并且利用像面最大弥散光斑的尺寸验证了系统的有效性。
It is very effective to measure the particle parameters of the high temperature plasma on the HL-2A Tokamak device by means of charge exchange recombination spectroscopy.In order to obtain signals of 480~650 nm in visible spectrum band and larger observing field in the tilted space geometry location,and satisfy the requirement of small fiber numerical aperture,an optical system with one mirror and four pieces of lens was designed with ZEMAX software.The performance of the system was verified by maximum diffusion spot on image surface.
