We might not give it much thought, but windows hold a special place in our daily lives. They help in entering natural sunlight, pure air, and gift us peeks into the world beyond. But have you ever heard about windows that you can’t even see?
Yes, believe it or not, there exist windows that are practically invisible. These special windows are crafted from materials that let visible light pass through but block out ultraviolet (UV) light. This makes them incredibly useful in situation where preventing UV radiation matters, like in the windows of spacecraft or medical imaging devices.
Two main materials play starring role in these invisible windows are:
- UV fused silica
- Magnesium fluoride
UV fused silica is a type of glass with ability for letting UV light through. Meanwhile, magnesium fluoride is a crystal clear material that is also a UV light champion.
This article will be your guide to know the characteristics, applications and advantages of these two essential optical elements.
UV Fused Silica Windows
UV fused silica is a high-purity synthetic material known for its exceptional transparency in the UV wavelength range. It is composed of silicon dioxide (SiO2) and is manufactured using a melting and forming process.
Properties of UV fused silica windows
The amorphous and homogeneous structure imparts several remarkable properties to UV fused silica windows:
- Transparency
- Low thermal expansion
- Chemical resistance
- High UV laser damage threshold
