SUMMARY

YMP-6115 blackbody radiation experiment apparatus is designed for university modern physics teaching. Blackbody is a pure temperatureradiator whose radiation is solely related to its temperature. YMP-6115 experiment apparatus adopts a voltage-stabilized bromo-tungstenlight source to approximate blackbody. By altering the current, blackbody radiation in different temperatures can be obtained. The radiationcurves can be measured by a NIR grating spectrometer and used to verify Wien's displacement law, Planck's law, and Stephan Boltzmann’s law. The internal optical paths and structures are visible to users. An Indium Gallium Arsenic detector ensures a high S/N ratio andsensitivity in the spectral range of 800nm-2500nm.

FEATURES

• Modular design, convenient for students to master the design principle and measurement principle.

• High quality indium gallium arsenic detector and high performance circuit system are used to make the whole set of experimental devices have good S/N ratio and sensitivity.

• Intelligent software design, each experimental module in accordance with the experimental principles and processes guided operation, so that students will mainly focus on the experiment itself, rather than academic software operation.
