William B Telfair, Clifford A Martin, Eugene I Gordon, William C Fricke: Ultraviolet radiometer. Taunton Technologies, Kramer Brufsky & Cifelli, December 5, 1989: US04885471 (11 worldwide citation)

An ultraviolet radiometer converts UV radiation to fluorescent radiation. An optical signal corresponding to the intensity of detected fluorescent radiation is converted to an electrical signal corresponding to the power or energy of the detected fluorescent emission. A monitoring element receives t ...
