UQG Optics

Lead Glass Windows
UQG custom made x-ray protection lead glass windows act as a protection barrier to harmful rays. Widely used in vacuum systems and sensitive instruments. They are an excellent radiation shielding glass.

Our custom made lead glass windows are manufactured in circular windows or plates in two grades of surface finish, either optically polished for increased flatness or thickness tolerance and from standard polished sheet materials.

We hold stocks of standard thicknesses supplying small and production quantities.
