A radiation source for both the visible and the infrared

Abstract

A radiation source with high output in both the visible and infrared spectral ranges has been developed, and its operating parameters are described. The hot element, a carbon composite board, is simple to fabricate as well as to operate. The source has been compared to both a tungsten strip lamp and a Nernst glower. For applications where both the visible and infrared ranges are of interest, this source allows for simplified experimental design.
