secondary spectrum

The apochromatic theory of optical system of wide spectral is discussed in this paper, emphatically in two aspects of suitable glass materials for correction of secondary spectrum and reasonably distributing each lens power.

本文对宽光谱光学系统的复消色差理论进行了论述，主要在玻璃材料的选择和光焦度的分配问题两方面进行了研究。

Using electro-imaging data, the paper uses ELAN program and program of pore spectrum analysis to analyze and study secondary porosity of Budat formulation in Hailar basin.

文中利用电成像测井资料，采用ELAN程序、孔隙频谱分析程序对海拉尔盆地布达特地层的次生孔隙率进行分析研究。

There is a different spherochromatism after the two systems secondary spectrum , spherical aberration and somatic aberration.

当这两种系统消球差、彗差及复消色差后会产生不同的色球差.

The resulting residual chromatism is known as secondary spectrum.

所得到的剩余色差叫做二次光谱.
