Kilner screen

a special viewing apparatus that allegedly reveals the invisible auras emitted by human beings. It is essentially a light filter, originally consisting of two pieces of glass separated by a layer of dicyanine A (a blue dye used in photographic emulsions); more recently manufactured Kilner screens are usually made with less toxic chemicals. Adherents claim that the inspection of human auras through such a screen can play a vital role in the early diagnosis of disease. Also called Kilner goggles. See also Kirlian photography. [Walter J. Kilner (1847–1920), British physician]
