A new method of measuring the refractive index of a prism using the critical angle is described. The accuracy of the technique and tolerances on angle measurements are discussed. Two standard prisms were measured using this method and the values agreed with those measured by the minimum deviation...
In the study of optical properties of low class crystal system,the identification of optic sign has important meaning to unknown crystal and mineral determination.From the refractive index and optical angle,with the mathematics tools,two methods are theoretically analyzed in this paper.They are not ...
In addition, the sensing performance of the system is researched by studying different the sensing medium refractive index. Finally, when the polarization angle is increased from 0° to 90°, the effect on the absorption performance of the structure is studied. The excellent performance of this ...
The critical frequency of ionosphere at linearity condition and the atmospheric refractive index formula are derived. 通过对线性条件下电离层临界频率和大气折射率公式的推导,并结合电离层电子浓度经验分布模型对电子浓度和大气折射率进行数值模拟,进而对电离层大气折射率的高度剖面图及其变化特性进行了分析,为微波卫...
DLS measurements were performed with a Malvern Zetasizer Nano ZS (Malvern, Herrenberg, Germany) equipped with a 633-nm He-Ne laser and operating at an angle of 173°. The software used to collect and analyze the data was the Dispersion Technology Software version 6.01 from Malvern. Five-hundre...
According to this equation, the intensity would appear to diverge at T = Tc; in the direction of the beam (e = 0), while at finite angle 0 this catastrophe would be averted by the term b sin2(0/2) in the denominator. A plot of 1/1 vs. T would remain almost linear until b ...
When we analysed the ability of USP7 to form dimers in size-exclusion chromatography with multi-angle laser light scattering detection (SEC-MALLS), we observed no dimerization for full-length (FL) USP7 (injected at 20 µM, peak elutes at ~4 µM) and only partially for the constr...
The key difference between refractive index and critical angle is that refractive index is the ratio of the velocity of a light beam in the air to the velo

Both features are present in the described simple critical-angle method of measuring the refractive index of a transparent solid. It is not as accurate as the well known spectrometer method, properly done, but is much less demanding on eyesight. Much of the necessary apparatus is likely to be...
