PHOTOELECTRIC SPECTRUM ANALYZER Russian patent published in 1997 - IPC

FIELD: spectral instruments with photoelectric recording of radiation. SUBSTANCE: spectrum ANALYZER has light source. Polychromator with optical input and optical outputs connected optically to photoreceivers is mounted in direction of light source radiation. Spectrum ANALYZER has also stable radiation source, light guide consisting of different-diameter monoblocks, and shutter located between stable radiation source and light guide input. Shutter is mounted for interruption of optical communication between stable radiation source and light guide. Another shutter is mounted at optical input of polychromator for its interruption. Spectrum ANALYZER has also shutter control assembly the output of which is coupled kinematically to shutters. EFFECT: higher accuracy of analysis. 1 dwg
