Here is a link where you can see UV percent transmission for the various Schott glasses commonly found in HP beds:

There is a new type called VIT available (very hi transmission), but not sure who makes it, or what the %T values are. It is single layer I am told, blocking some visible light, some UVB, and all UVC.
