WebHow does a radiometer work? When light rays hit the vanes of a radiometer, the black sides of the vanes absorb the rays better than the white sides. This causes the black side to become hotter than the white side (thermal energy). When molecules in the air hit the vanes heat energy is transferred to them. What does a spectroradiometer measure? WebSpectral (i.e., wavelength-dependent) radiation is intensity of output from a radiation source (e.g., sun, electric lamp, reflected radiation from a surface of interest) as a function of wavelength. Radiation spectra vary for different radiation sources and conditions. Radiation spectra can be used to characterize radiation sources.

WebMar 21, 2012 · The usual method used to measure tiny torques is a device called a quartz fiber torque balance. One would suspend the balanced vane assembly in a suitable low pressure environment from a thin quartz fiber. At the bottom, just above the vanes, one would mount a small mirror. The radiometer is made from a glass bulb from which much of the air has been removed to form a partial vacuum. Inside the bulb, on a low-friction spindle, is a rotor with several (usually four) vertical lightweight vanes spaced equally around the axis. The vanes are polished or white on one side and black on the other.
