Do you mean shooting images that contain both UV and IR, but no visible light? I think the nearest thing to this would be the ZWB1 / UG11, probably in 3mm thickness. This passes much more UV than IR, but because there is so little UV compared to IR that gets through the atmosphere it should result in an image that is more balanced between UV and IR.
I&#039;m not sure of a lens that would work well for this though other than something really expensive like the Coastal / Jenoptik UV-Vis-IR APO lenses. As most lenses will likely have quite a bit of focus shift between UV and IR.]]></description>
