Description

In the experiment P5.5.1.1, the irradiance is measured using the Moll’s thermopile, and the luminous flux is measured using a luxmeter. The luxmeter is matched to the spectral sensitivity of the human eye V (λ) by means of a filter placed in front of the photoelement. A halogen lamp serves as the light source. From its spectrum, most of the visible light is screened out using a color filter; subsequently, a heat filter is used to absorb the infrared component of the radiation
