FIELD: physics.
SUBSTANCE: light from a reference source is broken down into a reference linear spectrum which is compared with the spectrum of the investigated star. Light from the reference source is first passed through an entrance slit, a collimator, a diffraction grating and a camera lens to form an image of the reference spectrum on a mask which blocks bright lines, after which the remaining spectrum is collected by a collector lens and directed to the main astronomical spectrograph, wherein the reference spectrum is compared with the spectrum of the investigated star.
EFFECT: higher measurement accuracy.
