Description

LEOI**3 is specifically designed to measure blackbody radiation energy or the radiation energy of an emission light source. This system can automatically record the radiation spectrum of an emission light source. By varying the color temperature of the light source, the phenomenon as described by Wien&#**9;s displacement law can be observed through the recorded radiation spectrum of the light source. This system can be used to precisely verify the Planck&#**9;s law and Stefan-Boltzmann&#**9;s law. Based on the Planck&#**9;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.
