Optical filtering element |
| abstract |
Optical filtering elements having two opposed surfaces and including at least one thin layer of stable non-reflective fluorescent material provide transparent articles which, when exposed to incident visible light at one surface of the fluorescent layer, absorb certain wavelengths within the fluorescent layer and emit longer but still visible wavelengths at the opposed surface of the fluorescent layer. Methods of forming such optical filtering elements include providing a thin coating or layer (12) including stable fluorescent material on an optical element (14) by means of a solution or coating composition including stable fluorescent material, or forming transparent sheets or films (2) containing stable fluorescent material and utilizing them as optical filtering elements or incorporating them in an optical structure. In order to avoid glare and reflection of fluorescent light at the incident side, preferred embodiments require layers of stable fluorescent material which are about 1 mil (0.0254 mm) or less in thickness. |
