Lead Glass Disks are used in applications where there is a risk of x-ray exposure through an unshielded viewport. The Lead Glass disks can be attached to the air side face of UHV viewports.
For safety reasons, we recommend that they are held in place such that they cannot be removed unless the vacuum seal is broken.
The lead glass disks are 6mm thick and have a lead thickness equivalent of 1.5mm for X-ray sources up to 150 kV.

|Note: It is the responsibility of the user to check for radiation leakage from the system when using viewports fitted with lead glass disks.|
Having zero length these viewports offer the best solution for a viewing window for your vacuum chamber.
Avoiding spurious results when working with low energy particles within the vacuum system, by removing the possibility of static charge build up on the viewport.
