The experimental unit contains a blackbody emitter with a thermopile for investigation of thermal radiation, a light source with luxmeter for illuminance measurements, and absorption plates with thermocouples for investigation of Kirchhoff's laws. The intensity of thermal and visible radiation can be adjusted. Color filters and apertures expand the range of experiments. Measured values are displayed digitally on the measurement unit. At the same time, the measured values can also be transmitted directly to a PC via USB. Data acquisition software is included.
