Corning Med-X Glass

Corning Med-X Glass provides high-quality, transparent and safe protective shielding against X-ray radiation for medical, technical, and research applications.

The X-ray glass's high lead and barium content, and wide thickness range, provides optimum shielding against radiation from equipment operating in the 80 to 300 kV range.


Corning Med-X Glass is supplied as polished plates from 3.5 mm to 20 mm thickness with dimensions up to 2800 x 1400 mm (54 ” x 108″).

  • This allows architects to design viewing windows with a wider field of vision to maximize the observation requirements of the diagnostic operators.
  • Smaller sizes can be cut to meet most customer requirements.
  • All cut edges are ground and finished with safety chamfers.

Laminating/ double glazing:

Corning Med-X Glass is suitable for laminating using polyvinyl butyral (PVB) inter-layers and can also be fitted into sealed, double-glazed units for insulation purpose.

Corning Med-X Glass is compatible with a large range of installations and other viewing applications such as:

  • Viewing windows for X-ray, angiography, CT scans
  • Screens for medical diagnostics
  • Protection windows/glove boxes in laboratories
  • Airport security X-ray screens
  • Lenses for safety goggles
