I've been tying up some baitfish patterns using Hareline Dubbin's Ice Dub UV dubbing material. I got to thinking, "How do I know that this dubbing material really reflects UV light and how much?" Since we humans can't see UV light, for the most part, we can't just look at the dubbing material to tell. Also, is the dubbing material 100% UV reflective or are only 10% or less of the fibers UV reflective? I then remembered that we have a foot long UV light that we used to use for detecting where our previous cats used to pee on the walls. It is a pretty powerful UV light, using 3 D-cell batteries. So, I shined this UV light on the UV dubbing material, and to my surprise the dubbing material didn't light up or glow at all, not a bit. I know the UV light works because white paper glows, and some clothes in my closet glow, and on the carpet I can see spots where my current cat has thrown up. I did a bit of research online and found out that when I shine my UV light on something, when we see something light up or glow (like cat pee or clothes in my closet), we are seeing UV fluorescence, not UV reflectiveness. The UV light is absorbed and then some of the absorbed light is emitted (or fluoresces) in a visible wavelength that we humans can see. We cannot see reflected UV light. So, my question is if there is an easy method to determine if my UV dubbing is really UV reflective and by how much? I read online that it can be done with fancy photographic equipment and lenses, but I don't want to spend the money to do that.
