A Portable Spectrograph for Making Spectrophotometric Measurements of Distant Objects,
Abstract
The portable spectrograph PS-2 was designed for making spectrophotometric measurements of objects located at considerable distances from the observation point under natural conditions with sunlight. The spectrograph gives the spectrum of the object being measured in the spectral region from 400 to 800 nm, a black and white photograph of the object and also a photograph of a clock dial which shows the time the measurements were made. In addition, a reference radiation source is built into the spectrograph. When a spectrophotometric measurement is made of this source through a step attenuator, it allows one to calibrate the photographic material and to obtain the measurement results in absolute units.
