The design of optoelectronic devices fabricated from III-nitride materials is aided by knowledge of the refractive index and absorption coefficient of these materials.

对三族氮化物材料而言，拥有其反射率及消光系数的知识是有助於制光电元件设计的制造。

It is based on the analysis of reflectometric interference spectrum and by this means, optical constants, such as extinction coefficient, refractive index, absorption coefficient and thickness, can be calculated with a high precision.

该方法是一种高精度的测量方法，与透射光谱分析法相比，反射干涉测量方法对于薄膜系统的载体要求较小，可以是透明载体，也可以是非透明基底，可以是金属载体，也可以是光纤端面。

Being of the achromatic color of maximum lightness; having little or no hue owing to reflection of almost all incident light.

最浅淡的非彩色颜色；因为反射了几乎所有的入射光而只有很少的颜色或者没有颜色。

Color The achromatic color of maximum lightness; the color of objects that reflect nearly all light of all visible wavelengths; the complement or antagonist of black, the other extreme of the neutral gray series. Although typically a response to maximum stimulation of the retina, the perception of white appears always to depend on contrast.

白色：光亮度最大的一种无色；能反射几乎肉眼可见的所有波长光线的物体颜色；黑色的互补色或对抗色，中性灰色系列的另一种极端色，尽管白色通常是对视网膜所受最大限度刺激的反应，人们对它的感知却总是显得依赖于对比

Optimal design of rhomb-type retarder can improve achromatism according to the principle that the light arising total reflection has a phase transformation in the medium surface.

根据光在介质表面全反射时发生相变这一原理，分析了一个具有3个全内反射面的菱体型延迟器件，得出了相位延迟δ与全内反射角θ和相位延迟δ与介质折射率n的关系。

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。
