摘要：
FIELD: measuring equipment.SUBSTANCE: invention relates to the field of measurement technology and relates to a Raman gas analyzer. Raman-gas analyzer includes a continuous laser, a rotary prism, a lens focusing laser radiation in the center of a sealed cell equipped with two windows for transmitting laser radiation and one window for outputting scattered light, two lenses, a holographic filter that blocks the radiation in the laser wavelength region, a spectral instrument associated with a multi-channel detector, a control unit and a personal computer. Cuvette is equipped with a pressure sensor and two solenoid valves. Small-sized gas compressor is connected to the inlet of the gaseous medium. Outside the cuvette, opposite to its windows, designed to transmit laser radiation, two identical spherical mirrors are installed, their mirrors facing each other the way multiple passage of laser beams through the cell is provided for focusing and crossing at two points located on the optical axis of the lens to colle
