<P>PROBLEM TO BE SOLVED: To provide a multicomponent laser gas analyzer which achieves exclusion of the influence of aberrations and extension of an optical frequency band capable of being propagated and accurately detects gas components of a plurality of measurement object gasses absorbing light from visible light to near infrared light. <P>SOLUTION: Optical systems reducing the influence of aberrations are employed as a light emitting optical system and a light receiving optical system. The extension of an optical frequency band is achieved by a multimode optical fiber, coupling means, and branching means. Thus the multicomponent laser gas analyzer accurately detects gas components. <P>COPYRIGHT: (C)2012,JPO&INPIT |
