A Portable Spectrophotometer for Geophysical Applications
Specifications, design considerations, and construction of an advanced spectrophotometer are discussed. This spectrophotometer represents a significant improvement over existing light measuring instruments. It is designed to measure light intensities in the visible spectrum (0.4 - 1.1 microns) with...
