Influence of Gaseous Species on Thermal Infrared Imaging
For most practical applications of thermography, gases like air are just the media through which an object's infrared radiation must propagate before it is detected. For any quantitative analysis, the extinction of radiation due to the gas must be known. In air, the constituents which lead...

Combustible Gas Safety Monitoring: Infrared vs. Catalytic Gas Detectors
When designing a combustible gas safety monitoring system for oil/gas, petrochemical or other applications, how do you decide whether to use infrared or catalytic gas detector technology? Both sensing technologies have their advantages dependent upon your application's specific requirements...

Applications for the IMV-4000 Multi-Channel Infrared Microscope
infrared micro-spectrometers (micro-FTIR) were first used in microscopic characterization. As well as measuring the spectra of microscopic sites, such as impurity analysis in manufactured products, early micro-FTIR was used for much the same purposes as normal FTIR. Recently, however, it has...

Machine Vision Industry Focus: Putting Light to Work
is done, the beef has long since been shipped to supermarkets, having been graded by visual techniques. To provide a more accurate determination of beef tenderness, a clever designer developed a test that uses near infrared (NIR) reflectance spectroscopy. The spectrometer mounts above a conveyor belt...

Automated Optical Positioning Helps Automate FT-IR Analysis
The incorporation of software control to infrared spectrometers and in particular infrared micro spectrometers, has provided an important capability for automated analysis. Software control of infrared optics allows methods developed by scientists to be used by less-skilled personnel or, in many...
