Applications


Aerospace
Glass and glass components play a key role in the aerospace sector. They play an important part in protecting electronics, sensors, and navigation equipment from the harsh pressure and temperature environments the sector encounters, where reliability and performance are paramount.


Medical
There are many uses of glass and glass components in medical applications. From optical windows used in laparoscopic devices for keyhole surgery to X-ray transmission windows in radiation devices, glass plays an important role in the ever-evolving sector.


Optics
The transparency, durability, and precision of glass and glass windows makes it an ideal material for use in optical devices. Analytical equipment, measuring instruments, microscopes all utilize glass in some ways, as do more personal devices such as smart phones and cameras, where quality and clarity of image as become ever more important.


High Vacuum
Vacuum sight glasses are vital for inspection, monitoring and measurement of substances or components in high vacuum compartments. Particularly important in gas and oil industry, the low thermal expansion and high strength of glass windows, allow for bonding to metal housing without breaking vacuum.
