Experimental verification of a multiband system for non-contact temperature measurements

July 28, 2011

Proc. SPIE 5258, 198 (2003); doi:10.1117/12.544574 Conference Title: IV Workshop on Atomic and Molecular Physics Conference Chair: Jozef Heldt Abstract Adam Mazikowski and Marcin Gnyba Gdansk Univ. of Technology (Poland) Recent studies about non-contact temperature measurement concern passive multiband radiometric systems. These systems give a potential possibility of accurate temperature measurements in case of unknown [...]

Noncontact multiband emissivity measurements

June 12, 2011

Proc. SPIE 5124, 240 (2003); doi:10.1117/12.517121 Conference Title: Optoelectronic and Electronic Sensors V Conference Chairs: Wlodzimierz Kalita Abstract Adam Mazikowski Gdansk Univ. of Technology (Poland) During last decade an increasing interest in passive multiband systems for temperature measurement was noted. However, recent studies showed that multiband systems are capable of producing accurate results of non-contact [...]

Fluke Calibrator Video

October 24, 2010

Emissivity makes a temperature difference for infrared thermometers. In the YouTube video below, Frank Liebman, an engineer with Fluke Corporation’s Hart Scientific Division demonstrates the impact that surface emissivity has on temperature measurement and temperature calibration using a modified Fluke blackbody calibrator and Fluke Thermal Imager. We were surprised to see that no one commented [...]

Electro Optical Industries BB Emissivity Coatings

November 5, 2009

Electro Optical Industries (EOI) uses one of two high emissivity coatings on the surface of its blackbodies. The EOI mid-temperature coating is used on both cavity and flat plate blackbodies that have a maximum operating temperatures of up to 210 °C.

Blackbody Emissivity Primer

October 30, 2009

From the Electro-Optical Industries website: “Effective emissivity is the ratio of the total amount of energy exiting pharmacy websites a blackbody to that which is predicted by Planck’s law. This is the value most frequently referred to as “emissivity”. Effective emissivity of a cavity type blackbody will normally be much higher than the surface emissivity [...]
