Product Description
This product is an experimental teaching device used in laboratories to verify the transfer and variation of radiative energy. The platform includes two radiation sources: a thermal emitter and a light emitter (both with adjustable radiation power).
Thermal radiation is detected using a radiation sensor, while light radiation is measured using an illuminance meter. Various optical components are installed on an optical bench between the emitter and detector, and the distances between components can be read from the scale on the optical platform.
By rotating the illuminance meter, the influence of incident angle on radiation intensity can be studied. The supporting optical components are used to investigate the reflection, absorption, and transmission properties of different materials under varying wavelengths and temperatures.
Through experiments, fundamental heat transfer laws such as Kirchhoff’s radiation law, the Stefan–Boltzmann law, Lambert’s distance law, and Lambert’s cosine law can be verified. Measurement values are displayed digitally on the measurement amplifier and can also be transmitted directly to a PC via USB for further data processing.
These experiments help students understand the fundamentals of thermal radiation, develop related technical skills, and enhance innovation and experimental design capabilities.
