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.
