The result indicates that in the designed center of the wavelength, the retarder is not only confined within the low dispersive medium, but high-index material with higher dispersion can also obtain good achromatism, and at the same time the bigger angle of total reflection can improve achromatism of the phase retarder.

从全内反射相变方程出发,以菲涅尔菱体为例,分析了消色差相位延迟器的相位延迟量随折射率变化的光谱特性,结果表明:在所设计的中心波长处,延迟器件不仅仅局限于选择低色散的材料,色散较大的高折射率材料制作的延迟器件也可以具有良好的消色差性,且较大的全内反射角有利于改善延迟器件的消色差性。

The new apochromats were rare instruments, however, as totally apochromatic reflectors began to dominate astrophotography.

然而,当这种新型复消色差镜还是很稀罕的时候,真正的全消色差折射镜正将主宰天体摄影领域。

According to thin film polarization effect and eigenmatrix,the Fresnel retarder s achromatic width is expanded by evaporating dielectric membrane in two total-reflection surfaces of the rhomb.

根据薄膜的偏振效应,从薄膜的特征矩阵出发,通过在菱体的两个全反射面蒸镀光学介质膜的方法拓宽了菲涅耳菱体型相位延迟的消色差宽度。
