Here are a few new photos. The tapered light pipe seems to work pretty well for a quick prototype. I think I can squeeze a little more efficiency out of it by chemically “silvering” the light pipe (it will probably be a week or two before I have he time to do that). I should also have some resin tests exposed through a dlp projector within a month or so. This will give me an idea whether I need to scale up the uv led wattage or not.
