Integrated dual-light-source seat applicable to roadside respiratory zone air quality on-line monitoring system

Abstract

The invention discloses an integrated dual-light-source seat applicable to a roadside respiratory zone air quality on-line monitoring system. The integrated dual-light-source seat comprises an infrared light source, an ultraviolet light source, a beam coupling lens, a focusing mirror, a base and a cover plate, wherein the base adopts a semi-closed cubic structure, the infrared light source is fixed on a side surface of the base, the ultraviolet light source is fixed on the bottom surface of the base, the ultraviolet light source and the infrared light source are mounted with an included angle being 90 degrees, the beam coupling lens is fixed in the base, the focusing mirror is fixed on a side surface, opposite to the infrared light source fixing surface, of the base, and the cover plate is fixed on the unclosed side of the base through a screw assembly. The integrated dual-light-source seat has the advantages that an optical signal utilization rate is high, and high-power light sources can be used; the aperture of a light spot of an emitted light path is large, and the seat is applicable to a long-optical-path optical system; the seat is simple in structure, small in size, convenient to debug and good in stability and can be matched with different devices for use.

Description

technical field [0001] The invention relates to an integrated double light source seat suitable for an air quality online monitoring system of a roadside breathing belt, and belongs to the field of applied optics. Background technique [0002] At present, the multi-optical coupling device has the problem of poor applicability. For example, the common dual light source coupling method consists of two methods: common optical axis and optical fiber. The common optical axis method has a complex system structure, many lenses, and has requirements for the structure and shape of the light source. It is not conducive to the use of high-power light sources; the optical fiber coupling method has problems such as large loss of optical signal energy and small spot diameter, and is not suitable for long optical path systems.
