Abstract

Stray light in a spectrophotometer which is caused by internal reflection in a 60° prism has been investigated. The light appears as a “ghost” line at the spectrum position of minimum deviation, of an intensity corresponding to about 0.1 percent of the energy of the total spectrum. Means of eliminating or utilizing it are discussed.
