Summary

Non-free media information and use rationale true for Planetary Fourier Spectrometer
Description	An image of the interferometer used in the core of the Planetary Fourier Spectrometer.
Source	http://www.pfs-results.it/index.php?id=pfs
Article	Planetary Fourier Spectrometer
Portion used	Single image
Low resolution?	Yes
Purpose of use	This image is used as the primary identification of the scientific instrument featured, and to support critical commentary, in an article whose primary topic relates to the use of instrumentation concerned and the experimental work in which it is involved. As this item is a unique and complex item of hardware, of which representative images are rare, its use is considered fair use.
Replaceable?	Images of instrumentation of this kind of unique, and images of a specific complex item rare, thusly as no known free images of this item exist, and an image that was not of the equipment would fail to be representative, it is not possible to provide a 'free' replacement for this image.
