Zinc selenide (ZnSe) is an important optical material widely used in fields such as infrared optics and optoelectronic devices due to its excellent infrared transmittance. As a key parameter for measuring the optical performance of materials, the transmittance of zinc selenide directly affects the transmission efficiency of infrared light signals. So, what is the transmittance of zinc selenide? Let's take a look together!
The transmittance of zinc selenide is mainly affected by factors such as material purity, crystal structure, surface quality, and optical processing. In theory, high-quality zinc selenide crystals have extremely high transmittance in the infrared spectral range. In practical applications, high-quality zinc selenide materials that have been carefully prepared and processed can achieve a transmittance of over 90% in a specific infrared wavelength range, and even close to 100% in certain specific wavelength bands.
However, the transmittance of zinc selenide is not fixed and unchanging. The purity of materials, defects in crystals, surface roughness, and possible scattering introduced during optical processing may all have an impact on transmittance. Therefore, the actual measured transmittance values may vary due to factors such as material quality and testing conditions.
In order to obtain high transmittance zinc selenide materials, strict control is required from multiple aspects such as preparation process, crystal growth, optical processing, etc. In addition, for the transmittance testing of zinc selenide materials, high-precision optical testing equipment needs to be used under standard testing conditions.
