Blackbody is a complete temperature radiator, and its radiation ability is only related to its own temperature. The experiment uses a stabilized Bromine Tungsten light source to simulate a blackbody, and obtains blackbody radiation at different color temperatures by changing the power supply voltage. A NIR Grating Spectrometer is used to measure blackbody radiation curves with different color temperatures to verify Wien Displacement Law, Planck's Law and Stefan-Boltzmann Law.
BEM-5738 Blackbody Radiation Experiment adopts open structure design, students can intuitively observe the internal light path and structure composition, helping students understand and master the experimental principle. At the same time, InGaAs detector is used to ensure higher signal-to-noise ratio and sensitivity in the 800nm-2500nm spectral range. Intelligent software frees students from complex software operations and enables students to focus more on the design, principle and content of experiment.
