FIELD: optical instrument engineering.
SUBSTANCE: modulator has non-monochromatic radiation source, polarizer, first crystal, first analyzer, and second crystal, second analyzer which units are connected together in series by optical coupling. Modulator also has control electric field generator connected with second crystal. Optical axes of first and second crystals are perpendicular to direction of radiation and are parallel to each other. Axes of transmission of polarizer and analyzers are parallel to each other and are disposed at angle of 45o to optical axes of crystals.
EFFECT: widened spectral range.
