![]() So the birds don't see "black decoys" if only the UV is missing. Birds see all the other wavelengths that we see in addition to UV. This is a common conclusion that many people reach after seeing our UV images. So conventional snow goose decoys really look black to geese? If an object glows brightly under a black light, it is absorbing UV. Some people mistakenly call fluorescent paint UV paint but it isn't. Blaze orange and other fluorescent colors do the same thing, just at different wavelengths. That's why a white t-shirt seems so bright under a black light, it takes the invisible UV and converts it to visible. Objects that glow under a black light are fluorescent - they absorb the UV and re-emit it as visible light. When our T-shirts glow under a black light, we are not seeing UV reflection. You’d need UV imaging equipment to see the UV light coming off a black light. This is the violet light we see when a black light is on. Black lights also emit a small amount of visible light near the lower end of our wavelength range. Can't a normal black light be used to test for UV reflection?Ī normal blacklight does emit UV but our eyes can't see it. Since the wavelength is not affected by reflection, we are still unable to see them and the surfaces do not look any different to us. They simply reflect the UV wavelengths rather than absorb them. Optical brighteners that are used in fabrics and detergents are based on this same effect. Fluorescent paint absorbs the UV portion of light and re-emits it at another wavelength – one that can be seen by humans. Isn't basic fluorescent white paint the same thing?įluorescent paint which looks bright under a black light is not the same thing as UV-reflecting paint. ![]() Only by using UV imaging equipment will you be able to see the difference. The colors of our paints will appear normal to human eyes but will possess the UV reflection appropriate for that feathered area of the bird. ![]() Parker Decoy Paint with UVision looks and acts like normal oil based paint. UVision Technology Does the paint look like normal flat paint to us? ![]()
