Description

technical field [0001] The present invention relates to a dust monitoring optical system, more specifically to a light cone-based forward scattering dust instrument optical system, which belongs to the field of environmental monitoring devices. Background technique [0002] With the advancement of ultra-low emissions in the field of environmental protection, forward scattering dust meters have gradually become mainstream. The optical system undertakes the task of transmitting the measurement signal back to the light source for measurement. Most of the technical solutions are realized by utilizing the flexible light guiding feature of the optical fiber. The structure is simple and the work is reliable. A collimating lens is used at the light entrance to couple the incident measurement light into the optical fiber for transmission, and then incident on the sensor for measurement. However, this method has low coupling efficiency and large energy loss. It is used in a high-te...
