Scope
Analytical Fourier-spectrometer AF-1 is designed for spectral investigations and analytical measurements in a spectrum infra-red region.
Fourier-spectrometer AF-1 can be equipped with the following ad-on devices developed and manufactured in STC of Unique Instrumentation of RAS:
- attachment for measuring mirror and diffuse reflection;
- attachment of multiple disturbed complete inner reflection приставкой многократного;
- capacitor for obtaining an object spectra;
- diameter 1.5 mm;
- liquid cells with different thickness of liquid layers with crystal windows, transparent at corresponding spectrum regions жидкостными;
- single-pass gas cells 10 cm long;
- multi-pass gas cell with windows of different materials with optical path length from1 to 8 m.
