ATR-spectroscopy aboard landers MATROS

Function

Registration of Attenuated Total Reflection (ATR) spectrum of a sample, contacting with the ATR-prism. The goals: Description

The Instrument includes miniature Fourier-spectrometer and IR-source, changeable or cleanable ATR-prisms.

The design is based on the experience in creating flight Fourier-spectrometers (FS-1/4, PFS) and in laboratory ATR-studies of minerals and biologic objects.

The ATR-technique was not used before in planetary exploration experiments and it’s development is aimed for future projects for Mars exploration.
