| 摘要 |
The present application provides a non-dispersive infrared gas sensor (100). The non-dispersive infrared gas sensor includes an infrared source (110), an infrared detector (120), and a waveguide (150) extending about the infrared source and the infrared detector. The waveguide includes a reflective diffuser (190) thereon, to promote scattering so as to reduce overall mechanical sensitivity. |
