The unit has been designed to demonstrate the fundamental laws relating to radiation. By performing a series of simple experiment the students may verify the relevant equation appropriate the behavior of radiations. Thermal radiation is a mode of heat transfer which differs significantly from the other two modes. The fact that radiant energy transfer occurs across a vacuum is often disturbing to students unless the theory relating to properties of electromagnetic waves has been presented. The engineer is not directly concerned with the mechanism by which heat transfer occurs, but a sound knowledge of the properties and laws relating to the topic are required. By performing a series of simple experiments the student may verify the relevant equations of radiation. The unit Thermal Radiation consists of electrically heated radiant heat and light sources together with a comprehensive range of targets and measuring instruments.


  • Heat source consist of a heating aluminum plate rated with Matt Black Finish.
  • Radiometer to measure the heat radiation
  • Consist of a bulb rated at 60 Watt, to produce a well distributed light
  • Lux meter to show intensity of light
  • Target plates consist of three types Polished, Grey and Matt Black
  • Temperature sensors bolted on target plates
  • Plane surfaces consist of three types of density known as Clear, Medium and Dark.
  • Variable aperture Consist of two plates with insulation on one side of the surface. The Insulated surface will be facing the heated surface during the experiment.
  • Software with service unit for computerized control of the unit
