Product Description:
Sapphire Window/optical sapphire window/sapphire glass windows
Optical windows refer to a piece of transparent optical material that allows light into an optical instrument.
They are pieces of optical glasses with ground and polished faces that are relatively parallel. Optical windows
are applied for protecting fragile optical components inside an equipment, they are adopted to isolate two
physical environments while allowing light to pass.

About sapphire glass
SAPPHIRE CRYSTAL (sapphire glass) generally refers to synthetic sapphire, generally used in the manufacture of the watch glass.
It is resistant to wear with tungsten titanium alloys and high-tech ceramics. but sapphire materials can wear resistance and
withstand the strong impact, and some of the same or higher hardness of the material (e.g., millstone, sandpaper, nail, granite,
concrete wall, and floor, etc.) so sapphire glass are not likely to scratch the surface of these materials.
