I am considering making a small studio space for a video I want to make.
It will have to hold a cubic meter of space in which I will have very small fluorescent objects 1 mm cube (see previous thread).
Since I am not expecting to have the most flaming hot UV light driving the fluorescence I want a very dark background and I have been looking into very black paints or whatever else might be available.
I am looking to cover something greater than 3 sq meters, maybe 4 or 5 (details not yet worked out).
I have of course found Vanta (Vertically Alligned NanoTube Array) Black (the blackest surface covering available), but it is very expensive (330 pounds for a few sq. inches), kind of a defense department controlled substance, requires high temps for application and is not available to me. Vanta Black absorbs 99.965% of the light that hits it. Its used in optics and satellites predominately. Cool video and SEM.
Alternatively, I have been looking into very black paints used in media productions (Rosco Supersaturated Velour Black, $21.15/quart) and have read a bit about black paint used in making optics.
I am guessing that there are probably several people on this forum who make their own telescopes, I am wondering what experiences people have had with very black paints, such as Albrecht, deep-Black optical paint (10 Euros/375 ml).

- Cost of covering a few square meters is an issue (the above prices seems reasonable to me), in addition to blackness.
- Should also not reflect UV since I will be shining that around to excite the fluorescence.
