description | Sensitive and selective gas measurements are crucial for a large variety of
applications, e.g., explosion protection. Optical gas detection is usually
based on the gas' absorption of infrared radiation (IR). It is the leading
technique in terms of accuracy, reliability, and economic efficiency. Since
most gas measurements are made in the two wavelength ranges of
(3 ... 5) and (8 ... 14) μm, a broadband IR
source is necessary. In this paper, we report on a novel thermal IR emitter
with high radiant power and a near-blackbody emission characteristic that can
be modulated electrically. The layout of the IR source had been optimized by
use of finite element analyses (FEA) in order to get an adequate electrical resistance as well
as a homogeneous temperature distribution and a minimum deflection of the
radiating element. Due to its excellent thermal isolation from the heat sink,
the electrical power consumption is very low. Operating temperatures of up to
1400 K are possible, so that the fabricated IR source features a very high
radiant power. Its application in gas analysis will improve the performance
and efficiency of gas measurement systems. |
