These ZB1 filters show reasonable ~75% transmission at 390nm
-ish with not much ~0, in the visible range.There is some minor 0-10% transmission between 700nm to 1000nm and more beyond that , but the camera's response should be falling heavily by then. See the ZB1 filter curve below in
red ....
Even I might have to get 1
