Lead glass disks options
Certain processes inside a vacuum system can generate X-Rays. These X-Rays are usually absorbed by the metal walls of the vessels but may be able to pass through a glass viewport. To protect against this hazard, we offer a range of leaded glass disks that fit into the recess on top of the viewport.
For safety reasons, we recommend that they are held in place in such a way that they cannot be removed unless the vacuum seal is broken. The lead glass disks are all 8 mm thick to accommodate a lead thickness of 1.5 mm for X-Ray sources up to 50kV.
