Large transparency: ZnSe contains a high transparency during the infrared spectrum, specifically in The three-twelve micron range, which makes it ideal for use in laser beam supply systems and thermal imaging devices.
The surface morphologies of ZnSe slender film were being analyzed making use of the sphere emission scanning electron microscope (FE-SEM) which arrives up with very-high resolution imaging at smaller Doing work distances and reduced accelerating voltages. The FESEM images with the ZnSe thin films which deposited on glass substrate at different thicknesses (a = 224 nm and b = 633 nm) are demonstrated in figure 4.
