Zinc selenide (ZnSe) is an important optical material, and its refractive index is one of the key parameters for evaluating its optical performance. So what is the refractive index of zinc selenide? Let's take a look together!
Zinc selenide has different refractive indices for light of different wavelengths at room temperature and pressure. As the wavelength increases, the refractive index of zinc selenide gradually decreases. For example, in the visible light range, the refractive index of zinc selenide is usually between 2.4 and 2.5. Within the infrared spectral range, its refractive index may vary. The refractive index of zinc selenide is also affected by temperature. As the temperature increases, the refractive index of zinc selenide will decrease. In practical applications, in order to obtain accurate refractive index data, it is necessary to consider the ambient temperature of zinc selenide.
The high refractive index of zinc selenide makes it widely used in the field of optics, and can be used to manufacture infrared optical components, such as infrared windows, infrared filters, etc. Its high refractive index can cause a large refractive angle of light inside zinc selenide, thereby achieving functions such as focusing, separating, or directing light. Zinc selenide also has advantages such as high transmittance, low dispersion, and good chemical stability, making it widely used in fields such as optoelectronic devices, lasers, and solar cells.
