| Abstract: | The possibilities for expanding the range of tuning of the wavelength isolated by a tunable interference light filter, based
on a combination of a nonuniform multilayer and a reflecting prism, are investigated. The degree of influence of the immersion
liquid on the lower limit of wavelength tuning is studied. That influence is shown to be limited. A connection between the
scheme for obtaining a nonuniform multilayer and the maximum wavelength of light reflected by the multilayer is demonstrated
theoretically. The working range of a wavelength-tunable filter, the nonuniform multilayer of which is based on holographic
photographic plates, is expanded by changing the scheme for obtaining the multilayer. The possibility of advancing into the
near ultraviolet by using other materials (such as bichromized gelatin) is demonstrated experimentally.
