Basic Thermal Physics: Heat Exchange and Infrared Radiation

Published in Kurt Ammer, Francis Ring, The Thermal Human Body, 2019

Radiant flux, dφ/dA, is the radiant flow per unit area (unit:W m−2). The radiant flux emitted by a surface is the thermal radiant exitance. The radiant flux incident on or passing through an area is the irradiance.

Firstly, the actual polymerisation light curing intensity (mW/cm2, radiant emittance) of each LCUs and each curing modes used in the current study was analysed and compared with the manufacturers’ claim. The actual mean light intensity recorded for both the monowave and the polywave LCUs were lower than what has been reported by the manufactures (Table 2). The polywave LCU had a higher standard deviation in the light intensity measured by the radiometer, compared to that of the monowave LCU.
