Abstract
An ultraviolet radiation protection evaluator for determining the effectiveness and protection rating of sunscreen. The apparatus contains a fiber optic probe for delivering Ultraviolet radiation directly to skin. The probe receives reflected and diffused ultraviolet radiation from the skin and transmits the same to a monochromator which performs a spectral analysis and evaluation on the reflected radiation. This information is transmitted to a computer having software for evaluating the readings. The readings are taken first on untreated skin then again on skin treated with a sunscreen. The software, via variables inputted to the computer, computes the ratio of the sunscreen data obtained from both the treated and untreated skin along with the product of the spectrum of the light and radiation source and the action spectrum of UV induced erythema and qualitively characterizes the sunscreen in relation to natural skin protection.
