CaF2 is ideal for any demanding programs exactly where its higher destruction threshold, reduced fluorescence, and large homogeneity are valuable. It's well-liked in excimer laser purposes and commonly Utilized in spectroscopy and cooled thermal imaging.
The floor morphologies of ZnSe skinny film were being researched working with the sector emission scanning electron microscope (FE-SEM) which will come up with very-large resolution imaging at tiny Doing the job distances and small accelerating voltages. The FESEM photos of your ZnSe thin films which deposited on glass substrate at various thicknesses (a = 224 nm and b = 633 nm) are demonstrated in determine 4.
I found since the sellmeier equations that you just give down below the plot are supplying me incredibly distinct refraction indexes. Which one of these is suitable? The plot or even the sellmeier equation?

Minimal transmission outside of the infrared spectrum:ZnSe isn't as clear inside the visible spectrum, rendering it fewer well suited for use in optical devices the place seen light transmission is needed.
Thermal stability: BaF2 has very good thermal balance and is particularly effective at withstanding high temperatures, making it perfect for use in superior-temperature environments.
At Noni, our abilities to supply greater precision which looks difficult to Other folks are not only our pride and also a critical issue that sets us other than our competitors.
