Acousto-optic adjustable light filter with broadband

The invention relates to an acousto-optic adjustable light filter with broadband, which comprises an acousto-optic medium, wherein the acousto-optic medium is installed on a base; at least two transducers are installed on the surface of the acousto-optic medium; the surface of each transducer is plated with a surface electrode; each surface electrode is respectively connected with a matching network; the matching network is connected with a high-frequency socket; all the transducers are installed on the same surface of the acousto-optic medium through a linking layer; and the thicknesses of the transducers with each surface electrode are different. Because the two transducers are installed on the same side of the acousto-optic medium, the problem that the clamp is easy to damage the transducer which is installed in the front when the transducers are installed on the two surfaces of the traditional acousto-optic medium, thereby enhancing the finished product rate of products; and the transducers with different thicknesses drive the radio frequency signals with different frequencies, thereby obtaining the diffraction light with different wavelengths.
