Publisher's Synopsis
Excerpt from A New Spectropyrheliometer and Measurements of the Component Radiations From the Sun and From a Quartz-Mercury Vapor Lamp
The apparatus in the form of a Simple spectroradiometer will be useful in determining the decrease in the ultra-violet com ponent radiation with usage of a quartz-mercury vapor lamp, and in testing eye-protective glasses for opacity to ultra-violet light. The latter is a tedious (usually photographic) process which can be performed in a few minutes by utilizing the spectroradiometer described in the present paper.
This form of spectroradiometer, suitably modified, Should prove useful in measuring the spectral radiation from stars.
