Title

Spectroscopic design for analysis of sunscreen

Presentation Type

Poster

Abstract

We present the design of our solar spectrograph as part of the 2012 National Student Solar Spectrograph Competition. Our device will operate over the wavelength range from 280 to 400 nm with a resolution of 0.1 nm, sufficient to resolve Fraunhofer lines. This covers the ultraviolet A and B ranges, exposure to which is commonly associated with health risks. Our goal is to analyze the transmission of UV through various sunscreens to compare their efficacy. Our completed spectrograph will be used to take data at the national competition in Bozeman, Montana on May 16-19, 2012.
