It absolutely was observed the film thickness benefit believed by optical Investigation is within the worth received from profilometer measurements and thickness check with a utmost experimental error about ±four%.
The applied Swanepoel's method was utilized for computing the index of refraction and film thickness. That method depends basically over the extremes of your interference fringes of transmission spectra. The transmission and reflection spectra during the obvious area had been utilized to compute the Electrical power band gap values of ZnSe slim films. Also, the refractive index also calculated by Cauchy dispersion connection.
Moduli which were calculated as opposed to calculated are mentioned during the specification table For each relevant substrate.

ゲルマニウムの高屈折率と優れた硬度の独自の組み合わせを使用して、最小限のコンポーネント数で耐久性のある低出力イメージングおよびレーザシステムを構築します。
Determine 4 describes the actions of B/G ratio for both equally B3 and B1 structures in the investigated tension range. The attained B/G ratio for polycrystalline ZnSe are all much larger than 1.seventy five, implying which the polycrystal are inclined to conduct in the ductile manner. Determine four even more illustrates that the increase of hydrostatic force tends to enhance the ductile habits of ZnSe. The effect of force within the ductile of B3 ZnSe is larger sized than that about the ductile of B1 ZnSe.
This tab facts the key crystalline, optical, Actual physical, and thermal Houses presented for your substrates showcased on the remainder of the tabs on this webpage. Please contact Tech Support if you have any even more thoughts concerning these Houses.
Click on the photographs underneath or open the desk to the ideal to determine Thorlabs’ total collection of optics made out of BaF2.
The elastic anisotropy could be described the universal elastic anisotropy index AU that is developed by Ostoja–Starzewski44 for crystal with any symmetry. The AU is often composed as follows:
ZnSe windows have a relatively superior refractive index of 2.4, that makes them ideal for use in A selection of optical systems and apps. They may have a minimal absorption coefficient, that makes them perfect for use in higher-electric power laser systems, the place the Home windows need to remain transparent even underneath high intensity laser mild.
The calculated values In this particular operate are certainly not similar Together with the operate of Ji et al.39 by calculation. The versions of elastic get more info constants like a perform of pressure for each buildings are demonstrated in Fig. 2. It's noticed that each one the elastic constants for the two structures during the thought of choice of strain improve with increasing tension exhibiting a monotonic behavior. For both of those B3 and B1 phases, it is clear that C11 differ extra beneath the impact of force than Other folks. The elastic continuous C11 is related to the elasticity in size, that is adjusted With all the longitudinal pressure, as well as the C12 and C44 are represented the elasticity in condition. As a result, the tension has a much more important impact on elasticity in length. Also, the conduct of elastic constants for B3 period remains according to the do the job of Wang et al.37 by calculation.
