Product Details

Product Description:

LGT-5 is designed to measure radiant energy of black body radiation or emission of light source. The system can automatically record the radiation spectrum of the emitting light source. By changing the color temperature of the light source, the phenomenon is described by the Wien's law of displacement, which describes the quantitative analysis of the radiant light source that can be recorded. The system can accurately verify Planck's law and Stefan Boltzmann's law. Based on the Planck's formula, system software can calculate the theoretical radiation spectrum of an absolute blackbody at any given temperature. It can also correct the emissivity coefficient (ε) of a Tungsten-Bromine lamp at various temperatures.

Experiments:

1. Verify the Planck's law of radiation

2. Verify the Stefan-Boltzmann law

3. Verify the Wien's Displacement law

4. Study the relationship of radiation intensity between a blackbody and a non-blackbody emitter

5. Learn how to measure the radiation energy curve of a non-blackbody emitter
