Radiation source for gas sensor |
摘要 |
A gas sensor radiation source includes a filament in which microcavities having an opening diameter of about half of the absorption spectrum wavelength of a gas whose concentration is to be measured and a depth of twice or more greater than the opening diameter and a bulb enclosing, at a reduced pressure or with a noble gas enclosed therein, a filament. Thus, radiation can be efficiently made in accordance with the absorption spectrum of the gas to be detected.
