Abstract
A device for assessing sunscreen coverage on a person includes a casing a lens assembly extending from about a front facing surface of the casing and allowing transmissivity to light energy in a wavelength range of about 300 to about 400 nm. A filter is in optical communication with the lens assembly and having a high optical density above about 390 nm and a low optical density below about 390 nm. A sensor is in optical communication with the filter, the sensor having a signal/noise ratio that is greater than about 36 db. A controller is configured for receiving input from a user to control the device. A display screen may be in communication with a controller for displaying an image associated with the filtered light.
