Abstract
Tunable light filters are widely used for selecting different bands of wavelengths in the UV, visible and IR spectrum. Their advantages are simplicity, accuracy and high mono-chromaticity. By varying magnetic field it is possible to adjust the filter and select desired wavelength if necessary. In the paper a research on tunable light filters based on Fabry-Perot interferometer (FPI) is presented. These light filters can be tuned in the wavelength range from 400 nm to 1000 nm, in IR band of 8 - 12 μm, with spectral pass band width between 0.5 μm and 1 μm, out of band rejection than 10꞉1 with a resolution of 0.5 - 1.5μV.
