  • Two-band Fourier transform spectrometer (FTS) with dichroic Michelson mirrors
    Patent number: 5561521
    Abstract: Two dichroic mirrors (26, 30) and a dichroic beamsplitter (36) are introduced into the conventional Michelson Fourier transform spectrometer to accommodate two spectral bands. A conventional Michelson Fourier transform spectrometer (FTS) uses two mirrors (20, 22), one fixed (20) and the other moving (22). The present invention replaces each of the two mirrors (20, 22) with a pair of mirrors, one of which is a dichroic mirror (26, 30). The present invention involves inserting the first dichroic mirror (26) fixed in position between the beamsplitter (12) and the first plane mirror (20) and inserting a second dichroic minor (30), which can be moved in a direction normal to the plane surface, between the beamsplitter (12) and the second plane mirror (22). The first dichroic mirror (26) and second dichroic mirror (30) transmit long wavelength radiation and reflect short wavelength radiation.
