Substantial transparency inside the infrared spectrum: ZnSe is highly transparent from the 3-twelve micron variety, making it perfect for use in laser beam shipping and delivery techniques and thermal imaging units.
According to the acquired elastic constants, the elastic Homes for instance bulk modulus, shear modulus, Youthful’s modulus, ductile/brittle habits and elastic anisotropy for a perform of strain for polycrystalline of ZnSe are discussed in specifics. In the body perform of quasi-harmonic Debye model, the temperature and stress dependencies with the Debye temperature and warmth capability of ZnSe are acquired and reviewed inside the huge ranges.
I noticed as the sellmeier equations that you choose to give down below the plot are offering me pretty distinct refraction indexes. Which one of these is correct? The plot or even the sellmeier equation?
It shows superb CTE homogeneity and chemical security, which is regularly utilized in high-precision optical methods. Transmission facts and specs will not be presented for Zerodur for the reason that Thorlabs only provides reflective Zerodur optics.
Also known as the V-variety, the Abbe quantity is really an optical property that quantifies a fabric's dispersion, or variation in refractive index with respect to wavelength. It is actually defined with the equation
Delicate to scratches: ZnSe is pretty delicate to scratches and also other area defects, which may result in scattering and absorption of light. This causes it to be essential to handle ZnSe Home windows with treatment to stay away from damage.

Refractive indices, period-matching Instructions and 3rd buy nonlinear coefficients of rutile TiO2 from third harmonic generation.
The parallel, or incredible, axis will be the axis alongside which transmitted light-weight will endure no birefringence. It truly is parallel into the optical axis in the crystal. The perpendicular, or standard, axis is perpendicular to the zinc selenide optical axis.
