WebThis depends on whether or not you have a vacuum in the radiometer: The photons hitting the black side of the vanes will be absorbed transferring their momentum to the vane. Those hitting the white surface will be reflected transferring up to TWICE their momentum to the vanes. 1) In a vacuum: The above concept dominates and the white vanes ... WebWorking of Infrared Thermometers. Similar to visible light, it is also possible to focus, reflect, or absorb infrared light. Infrared thermometers employ a lens to focus the infrared light emitting from the object onto a detector known as a thermopile. The thermopile is nothing but thermocouples connected in series or parallel.
