Abstract. Principle optical schematics of the source with the possibility of spectral adjustment are analyzed. None of the existing tunable sources allows simultaneous rearrangement of the number of spectral lines, their position, and the half-width of a separate spectral line. Such spectral rearrangement is possible with the use of acousto-optic filtration together with a broadband radiation source. At the same time, the features of the acousto-optic filter cause the system low efficiency (5% or less), which limits the use of such a source, for example, in the spectral analysis of highly absorbing media. The choice of a schematic diagram of a broadband source interface system with an acousto-optic filter also affects the efficiency of the circuit and determines its additional characteristics - the complexity of components and dimensions. Results of simulation of the system operation performed using the optical design software Zemax Optical Studio, are reported to be in good agreement with the results of the experiment.
Keywords: spectrum tunable source, development of optical systems, light flux utilization factor, acousto-optic filter
